Answer 2

Can I help you in a few minutes, I'm helping two other people right now, won't take long! :)

Answer 3

okay thank you

Answer 4

Okay, let's do this :)

Answer 5

So, do you know the SOHCAHTOA rule?

Answer 6

no

Answer 7

@Jadeishere

Answer 8

the sine, cosine, and tangent of an angle. SOH stands for Sine equals Opposite over Hypotenuse. CAH stands for Cosine equals Adjacent over Hypotenuse. TOA stands for Tangent equals Opposite over Adjacent.

Answer 9

is it that?

Answer 10

Yep xD It is that
In relation to complimentary angles, there is a Complimentary Angle Theorem. Would you be willing to watch a video about it?

Answer 11

it explains it very well

Answer 12

im kinda in a rush thats the thing

Answer 13

@Jadeishere

Answer 14

Oh, well, the sin of an angle will be the same as the cos of the angles complimentary angle... DO you understand that? Kind of?

Answer 15

kind of

Answer 16

They're co-functions, which is how we know it works.

\[\cos(0) = \sin(90^{o} - 0)\]
\[\sin (0) = \cos(90^o - 0)\]

Answer 17

two cosine and sine are co functions ?
