Question

Find the exact value of sin^2 30 + cos^2 60 using identities and/or the complementary angle theorem

Answer 1

I know the answer is 1/2 but I am not sure how you get to that answer

Answer 2

I'm guessing 30 and 60 are in degrees?

Answer 3

sin(30 degrees) = .5
so sin^2(30 degrees) = .5^2 = .25

cos(60 degrees) = 0.5
cos^2(60 degrees) = .25

so ,25 + .25 = .5

Answer 4

Yeah they are in degrees sorry!
