Question

sin(2x) = 1+cos(2x)
Find all values of x.

Answer 1

i know that you have to use identities and factor to find equations that equal zero

Answer 2

now cos2x = 2cos^2 x - 1
sin2x = 2sinxcosx
so if we solve we will get
sinxcosx = cos^2 x

Answer 3

which gives you cos x =0 or cos x = sin x

Answer 4

now can you solve for x?
