does sin2(x)=sin(2x)?

8 sin²(3x) cos²(3x) = 2 [2 sin(3x) cos(3x)]² = 2 [sin(6x)]² = 2[1 - cos(12x)]/2 = 1 - cos(12x)

Graph y=-sin2(x-(3.14/4))

sin2 =2tan cos

cos2Acos2B + sin²(A-B) - sin²(A+B) = cos(2A+2B)

If sin(θ) = -1/√2, find sin2(θ). (Recall that sin2(θ) means (sin(θ))2.) sin2(θ) =

Did you solve sin2[sin^-1(pi/6)] and sin[2sin^-1(pi/6)] in the same way?

Sin2 theta =-1

Integrate sin² x dx

Sin²(theta)=0.25

Sin²(x)=0.25
