sin2x+sin2y=2sin(x+y)cos(x-y) Please helpp mee!! thank you sooo...

prove: 2sinx+sin2x = 2sin^3(x)/1-cosx

1+sin2x/sin2x=1+1/2(secx)(cscx)

(sec6x+sin2x)/(sin6x-sin2x)=tan4xcot2x

since sin2x+√3cos2x=2sin(2x+60) find the general solution for the equation sin2x+√3cosx=0 thank you...

given f(x)=sin2x and g(x)=cos(x+30) 1. solve for x if sin2x=cos(x+30) for x€[-180;180]

Prove that sin2x+cos2x-1/sin2x+cos2x+1=tanx

prove the identity sin2x-sin2y/sin2x+sin2y=tan(x-y)/tan(x+y)

A=cos2x+isin2x ,B=cos2y+sin2y hence prove that A-B/A+B=itan(x+y).

2tanx-sin2x÷2sin*2x =tanx

Sin2x+sin2y=2sin(x+y)cos(x-y)
