sine and cosine

Answer 4

Ok

Answer 5

unit circle, if sin(90) = 1,
then
remember sin is y values and cos is x values
if sin(90) = 1, we are looking at the topmost point onthe unit circle, or at (0, 1)

Answer 6

thats a circle btw 0-0

Answer 7

lmao

Answer 8

Answer 9

@jhonyy9 You coming

Answer 10

lets try again

Answer 11

The actual unit circle might be easier to visualize

Answer 12

we had a unit circle project-_-, we had to do that ^^^

Answer 13

yep, ty for the reference. basically sin(90) is when the angle is at 90 degrees, and when it is at 90 degrees the y value, is 1

Answer 14

basically go through the answer choices and see which ones are right and which are wrong, plug in all the angles into the unit circle and see which answer choice is right
