What’s that?

What is secant? The ladder distance? Its first 45° encompass 70 percent of the height and the 10th degree (from the 80s to 90s) only cover the 2 percentage. Secant begins at 1 (ladder in the floor, and the wall that wall) and then increases as it goes up. This is logical in that, at 0 degrees the dome is almost vertically.1
Secant is always larger than the tangent. However, as you climb to the summit of the dome, the height of your dome changes and level off. The ladder that leans to construct the screen should be wider than the screen itself does it not? (At massive sizes, if the ladder is almost vertical, they’re almost there.1 Secant/Tangent: The Wall. The secant will always be slightly larger.) A day comes when your neighbor constructs the wall on top of your dome.
Be aware that these values are in percentages . Your view! Your resale value! If you’re pointing at a 50-degree angle, tan(50) = 1.19. Can we get the most out of a situation that isn’t ideal?1
The screen is 19% bigger in comparison to its wall distance (the diameter that surrounds the dome). Sure. (Plug into x=0 and verify your intuition, ensuring that tan(0) is 0 and sec(0) equals 1.) What if we hung our screen for a movie up on the walls? It is possible to point at one right angle (x) and work out: Cosecant/Cotangent: The Ceiling.1 tangent(x) equals tan(x) = the height of the screen on wall distance from the screen: 1. (the screen always has exactly the same distance from the ground, so why is that?) secant(x) equals sec(x) equals what is the "ladder the distance" towards the screen. Surprisingly, your neighbor has decided to put up the ceiling over your dome, way beyond the beyond. ( What’s the matter with this fellow?1 Oh, the naked man-on-my-wall saga… ) We’ve come up with some exciting new words in the vocab. Now, it’s time to build an access ramp towards the ceiling, and also have a chit chat.
Imagine looking at the Vitruvian "TAN Gentleman" projected onto the wall. Pick an angle for the ramp and figure out: You climb up the ladder making sure that you "SEE what you can’t?". (Yeah the guy is not naked…1 will not forget the metaphor now don’t you?) cotangent(x) cotangent(x) = cot(x) is how long the ceiling is before it is connected. cosecant(x) with cosecant(x) = csc(x) = the length we will walk on the ramp. Let’s take a look at some things regarding tangent. The vertical distance that is traversed is always 1.1 Also, the width that the display is. Tangent/secant are the walls, COsecant and COtangent define the ceiling. It starts at zero and increases infinite height. Our instinctual facts are the same: You can continue to point towards the wall to achieve an infinity-wide screen! (That’ll cost you.) If you select an angle that is zero and your ramp is completely flat (infinite) however it never touches the ceiling.1
Tangent is simply a bigger variant of sine! It’s never smaller, and even when sine "tops off" when the dome expands, tangent is always growing. Bummer. What is secant? The ladder distance?
The the shortest "ramp" occurs when you’re pointing 90-degrees straight upwards. Secant begins at 1 (ladder in the floor, and the wall that wall) and then increases as it goes up.1 The cotangent is zero (we didn’t go along to the ceiling) while the cosecant has a value of 1. (the "ramp size" is at a minimum). Secant is always larger than the tangent. Visualize the Connections. The ladder that leans to construct the screen should be wider than the screen itself does it not? (At massive sizes, if the ladder is almost vertical, they’re almost there.1 Just a few days ago, I was unable to draw any "intuitive conclusion" concerning the cosecant.
The secant will always be slightly larger.) With the metaphor of the dome/wall/ceiling this is what we get: Be aware that these values are in percentages . What’s that? It’s the same triangle, only scaled to extend past the ceiling and wall.1 If you’re pointing at a 50-degree angle, tan(50) = 1.19. We have vertical components (sine and the tangent) as well as horizontal parts (cosine cotangent, sine) and "hypotenuses" (secant cosecant, secant). (Note that the labels will show the location where each piece "goes from to".1 The screen is 19% bigger in comparison to its wall distance (the diameter that surrounds the dome). Cosecant is the total distance from your body to the top of your head.) (Plug into x=0 and verify your intuition, ensuring that tan(0) is 0 and sec(0) equals 1.) Now comes the magic is in the details.1
Cosecant/Cotangent: The Ceiling. The triangles are similar to each other: Surprisingly, your neighbor has decided to put up the ceiling over your dome, way beyond the beyond. ( What’s the matter with this fellow? Oh, the naked man-on-my-wall saga… ) In The Pythagorean Theorem ($a^2 + b2 = C2$) we can see how the edges of each triangle are connected.1 Now, it’s time to build an access ramp towards the ceiling, and also have a chit chat. From the fact that they are similar, ratios like "height and width" must be equal with these triangular shapes. (Intuition take a step back from a huge triangle. Pick an angle for the ramp and figure out: The triangle appears smaller now from your perspective however the internal ratios haven’t changed.) cotangent(x) cotangent(x) = cot(x) is how long the ceiling is before it is connected.1 cosecant(x) with cosecant(x) = csc(x) = the length we will walk on the ramp.
It is the way we figure out "sine/cosine = Tangent/1". The vertical distance that is traversed is always 1. I’ve always tried to recall these facts, only to have them seem to pop out at us when they are visualized.1 Tangent/secant are the walls, COsecant and COtangent define the ceiling.
SOH-CAH TOA is a great shortcut, but it’s important to get an actual understanding first! Our instinctual facts are the same: Gotcha You’re Right: Keep Other Angles in Mind. If you select an angle that is zero and your ramp is completely flat (infinite) however it never touches the ceiling.1 It’s important to note … do not focus too much on one diagram, thinking that tangent is always less than. Bummer.
In the event that we extend the angle, we’ll reach the ceiling earlier than the wall. The the shortest "ramp" occurs when you’re pointing 90-degrees straight upwards. The Pythagorean/similarity connections are always true, but the relative sizes can vary.1
The cotangent is zero (we didn’t go along to the ceiling) while the cosecant has a value of 1. (the "ramp size" is at a minimum). (But you’ll be surprised to see that cosine and sine are always the smallest or tied together, as they’re encased inside the dome. Visualize the Connections. Nice!) Just a few days ago, I was unable to draw any "intuitive conclusion" concerning the cosecant.1 Summary: What Do We Need to Be Keeping in Mind? With the metaphor of the dome/wall/ceiling this is what we get: For the majority of us I’d suggest this is enough: What’s that? It’s the same triangle, only scaled to extend past the ceiling and wall. Trig provides an explanation of the structure of "math-made" objects like circles or repeating cycles.1
We have vertical components (sine and the tangent) as well as horizontal parts (cosine cotangent, sine) and "hypotenuses" (secant cosecant, secant). (Note that the labels will show the location where each piece "goes from to". The analogy between a dome and a wall illustrates the relationships between trig functions.1 Cosecant is the total distance from your body to the top of your head.) Trig returns percentages, which we can apply to our particular case. Now comes the magic is in the details. There is no need to learn $12 + cot2 =$, except for the silly tests that misinterpret trivia as understanding.
The triangles are similar to each other: In such a case, spend an hour to draw the dome/wall/ceiling design and add the labels (a man in a dark tan could see, wouldn’t you? ) Make an exercise sheet for yourself.1
