It’s logical when you consider that at 0° it’s almost vertically, but once you reach the top of the dome your height increases until it reaches a level. Tip: Trig Values Are Percentages. Secant/Tangent: The Wall. No one ever explained to me during my education that sine and cosine were percentages . The next day, your neighbor builds an extension of their wall directly in front of your dome.1 They can range from +100% to 100% or the maximum positive to null to the maximum negative. Oh, what a view! Your resale value!
Let’s say that I paid $14 in taxes. However, can we find a way to make the most of a difficult situation? You don’t know whether that’s a lot. Sure. But if I tell you that I paid 95% in tax, I know I’m getting scammed.1 What happens if we put our screen for a movie in the room?
Then, you point to the angles (x) and then figure out: Absolute heights aren’t very helpful If you have a sine of .95 I’ll tell you that you’re close to the summit of the dome. tangent(x) is tan(x) = the height of the screen from wall to the screen: 1 (the screen always has the same length along the ground, isn’t it?) secant(x) is sec(x) is sec(x) = "ladder length" from the screen.1 In a short time, you’ll be at the top, and then begin dropping again. We’ve got some new and fancy vocabulary terms. How do we determine the percent? Simple Divide the current value by the largest feasible (the diameter of the dome, or"the hypotenuse).
Imagine watching the Vitruvian "TAN GENTLEMAN" projected onto the wall.1 It’s the reason we’re instructed "Sine = Opposite/Hypotenuse". You climb up the ladder, trying to "SEE can you?". (Yeah it’s true that he’s completely naked… don’t forget about the analogy do you?) This is to determine the percentage! An alternative phrase could be "Sine represents your height, as a proportion of the hypotenuse". (Sine turns negative when your angle is "underground".1 Let’s look at a few details about tangent. Cosine is negative if your angle is in the opposite direction.) The size of your screen. Let’s simplify the equation by assuming we’re in the circle of unit (radius one).
It begins at 0 and then goes on to infinitely high. This means we can eliminate any division of 1, and instead declare sine = height.1 It is possible to keep pointing upwards and upwards on the wall to create an endlessly huge screen! (That’ll cost you.) Each circle is the unit circle that is scaled upwards or downwards to the size of your choice.
Tangent is a larger variation of sine! It’s never smaller, and even though sine "tops off" when the dome gets bigger the dome, tangent continues to grow.1 Find the connections in the unit circle, and then apply your findings to the particular situation you are facing. What about secant, the ladder distance? You can try it out: plug into an angle, and then see what percentage of length and width it can reach: Secant begins at 1 (ladder from the floor to an end of the wall) and increases from there.1
The sine’s growth pattern does not form an equal line. Secant is always larger than the tangent. Its first 45° encompass 70 percent of the height and the 10th degree (from the 80s to 90s) only cover the 2 percentage. The ladder that leans to build the screen has to be larger than the screen itself isn’t it? (At huge dimensions, when the ladder is almost vertical, they’re pretty close.1 This is logical in that, at 0 degrees the dome is almost vertically. However, secant always is just a little larger.) However, as you climb to the summit of the dome, the height of your dome changes and level off.
Keep in mind that the numbers are in percentages . Secant/Tangent: The Wall. If you’re pointing at a 50-degree angle, tan(50) = 1.19.1 A day comes when your neighbor constructs the wall on top of your dome.
The screen you’re viewing is 19% bigger that the length of the wall (the diameter of your dome). Your view! Your resale value! (Plug in x=0 and test your intuition to see if tan(0) = 0 and sec(0) equals 1.) Can we get the most out of a situation that isn’t ideal?1 Cosecant/Cotangent: The Ceiling. Sure. It’s amazing that your neighbor is now planning to construct an eaves on top of your dome, well beyond the sky. ( What’s up with this man? Oh, the naked-man-on-my-wall-incident… ) 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: It’s time to construct an elevator up to the ceiling and then have a quick chat.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. Choose the angle you want to build from and then work out: We’ve come up with some exciting new words in the vocab.1 cotangent(x) cotangent(x) = cot(x) is the distance the ceiling extends prior to when connecting. cosecant(x) to csc(x) = the length we can walk along the ramp, the vertical distance we walk is always one. Imagine looking at the Vitruvian "TAN Gentleman" projected onto the wall. Tangent/secant define the wall COsecant and COtangent describe the ceiling.1 You climb up the ladder making sure that you "SEE what you can’t?". (Yeah the guy is not naked… will not forget the metaphor now don’t you?) Our intuitions are similar: Let’s take a look at some things regarding tangent. If you choose an angle of zero the ramp will be smooth (infinite) but never reaches the ceiling.1
Also, the width that the display is. Bummer. It starts at zero and increases infinite height. The most compact "ramp" can be found when you are pointing 90 degrees straight upwards.
You can continue to point towards the wall to achieve an infinity-wide screen! (That’ll cost you.) The cotangent is zero (we did not move across the top of our ceiling) as well as the cosecant of 1 (the "ramp duration" is the shortest).1
