1/8(2sin2x-sin4x)= cosxsin^3x prove

when you have "y = 1/2sin2x". . . Does the equation have a vertical compression by a factor of 1/...

Solve: tanx - 2sin2x = 0 0°< or equal to x < 360°

How do you express sin4x as a trigonometric funcition of x using the identities? I think that you ar...

2sin2x+1=0

help! what ia 1/4(sin4x)? just to jump start this proof

Sin(x+y)cos(x-y)= 1/2sin2x+ 1/2 sin2y Help please I have no idea how to do this because my math c...

Prove that: (sinx-2sin2x+sin3x)/(sinx+2sin2x+sin3x)= -tan^2 x/2.

proof that (sinx+sin3x-2sin2x)/(sinx+sin3x+2sin2x)=-tan(x/2)

2sin2x = cos2x for - pi x pi

Factorise: 2sin2x−5sin x+3
