prove 2cos^2(x)-1=0

Solution

prove

2 cos^{2} (x) - 1 = 0

Solution

False

Solution steps

2 cos^{2} (x) - 1 = 0

Show that the two sides are not equal

\Rightarrow False

Popular Examples

prove (1+cos(2θ))(1-cos(2θ))=sin^2(2θ)prove

(1 + cos (2 θ)) (1 - cos (2 θ)) = sin^{2} (2 θ)

prove sin(x)-cos(x)=0 prove

sin (x) - cos (x) = 0

prove sin(2θ)+cos(2θ)=2sin(θ)cos(θ)+2cos^2(θ)-1 prove

sin (2 θ) + cos (2 θ) = 2 sin (θ) cos (θ) + 2 cos^{2} (θ) - 1

prove (tan^4(x)-1)/(tan^2(x)-1)=sec^2(x)prove

\frac{tan ^{4} ( x ) - 1}{tan ^{2} ( x ) - 1} = sec^{2} (x)

prove cos(270-θ)=-sin(θ)prove

cos (27 0^{\circ} - θ) = - sin (θ)
