Answer 1

@jdoe0001 i need some help

Answer 2

i know i get 0.587

Answer 3

hmm, I assuming you're meant to use the calculator.... so to change the sine to cosine and viceversa, just use the Cofunction Identities http://ichthyosapiens.com/School/Math/Trig/ch05CofunctionIdentities.jpg

Answer 4

so you'd end up writing cosine in terms of sine and sine in terms of sine, same value though

Answer 5

54

Answer 6

yeap, which just means that \(\bf sin(36^o) \Leftrightarrow cos(54^o)\)

Answer 7

okay thanks j
