Answer 4

nah at my schools it goes algebra 1 geometry algebra 3 and pre calc or discrete math im in geometry summer school

Answer 5

*algebra 2

Answer 6

use a co-function identity

Answer 7

for example, recall one of the co-function identities is:
\[\cos(u)=\sin(\frac{\pi}{2}-u)\]

Answer 8

wow that really confused me

Answer 9

why does it confuse you?

Answer 10

because this stuff is like another language to me

Answer 11

but why does the identity confuse you?

Answer 12

is it because you never seen it?

Answer 13

kinda this is my first time learning this

Answer 14

could you find cos(theta)
and sin(90-theta) using this right triangle ?
