Asked by Steve

Use the graph of y=sin2theta to find the value of sin 2 theta for theta=pi/4.

a--1
b-0
c-0.5
d-1

my answer is -1
Answered by Eric
C. 1/2

sin (pi/4) = 1/sqrt(2)
(1/sqrt(2))^2 = 1/2
Answered by Steve
Can't tell just what you mean. Ever heard of notation for powers (^) of arguments () ?

θ = π/4

sin(2θ) = sin(2*π/4) = sin(π/2) = 1

C is correct if you meant sin^2(θ)
