prove sin(2A)=2sin(A)

Solution

prove

sin (2 A) = 2 sin (A)

Solution

False

Solution steps

sin (2 A) = 2 sin (A)

Show that the two sides are not equal

\Rightarrow False

Popular Examples

prove tan(θ)cos(θ)csc(θ)=1 prove

tan (θ) cos (θ) csc (θ) = 1

prove sin^2(x+pi/4)-cos^2(x-pi/4)=0 prove

sin^{2} (x + \frac{π}{4}) - cos^{2} (x - \frac{π}{4}) = 0

prove tan^2(u)-sin^2(u)=tan^2(u)sin^2(u)prove

tan^{2} (u) - sin^{2} (u) = tan^{2} (u) sin^{2} (u)

prove cos(x)-cos(x)sin^2(x)=cos^3(x)prove

cos (x) - cos (x) sin^{2} (x) = cos^{3} (x)

prove sin^2(x/2)=(1-cos(x))/2 prove

sin^{2} (\frac{x}{2}) = \frac{1 - cos ( x )}{2}
