Question

what is tan(3π/4)? explain how you got your answer

Answer 1

just put it in the calc cx

Answer 2

yes but i can't use it for this

Answer 3

Well, remember that tan is sin/cos

So find sin 3π/4 = 1/sqrt(2) and cos 3π/4 = -1/sqrt(2) so that means that:

sin 3π/4 /cos 3π/4 = tan 3π/4 = 1/sqrt(2) / -1/sqrt(2) = -1
