Question

trig confuses me -.-

Answer 1

Trig is the best thing ever.. on the planet c:
besides calculus

Answer 2

You are a rare mouse.

Answer 3

-_-

Answer 4

:*

Answer 5

http://prntscr.com/b79jse How is this different that inside?

Answer 6

Trig is like a dungeon filled with pipes.
Everything connects back and forth to one another.

It's amazing how you can get from one identity to another.
Crazy looping back and forth paths that you didn't know exist.

Answer 7

that is why they call it "trickonometry"

Answer 8

No rae jay. It refers to shooting yourself bc its so hard.

Answer 9

trigger.

Answer 10

ahhyesh triggernometry i like that too

Answer 11

If you mean the difference inside and outside the circle.
Inside the circle r=1 so \(sin \theta = y\) and \(cos \theta = x\)

Answer 12

thats the same from inside tho?

Answer 13

In the table they're talking about points outside the circle that's why you have the r

Answer 15

its outside. you said r = 1 is only for inside.

Answer 16

nvm r is the same

Answer 17

This coordinate that they gave us corresponds to a circle of radius r,
not necessarily r=1.

We'll have to apply our Pythagorean Theorem to find the value of r,\[\large\rm x^2+y^2=r^2\]Plugging the coordinate into our formula,\[\large\rm 1^2+(\sqrt3)^2=r^2\]

Answer 18

This r value happens to be our `hypotenuse`.
We'll need that information for sine and cosine, ya?

Answer 19

oh the radius isnt the same anymore ;'c

Answer 20

why isnt x the radius?

Answer 21

http://prntscr.com/b79mym where would this point be? like on the circle.

Answer 22

because you're looking at the wrong circle.
Our point lies on some larger circle.
