prove sin(x)=-sin(-x)

Solution

prove

sin (x) = - sin (- x)

Solution

True

Solution steps

sin (x) = - sin (- x)

Manipulating left side

sin (x)

Use the negative angle identity:

sin (- x) = - sin (x)

= - sin (- x)

We showed that the two sides could take the same form

\Rightarrow True

Popular Examples

prove sin^2(u)(1+cot^2(u))=1 prove

sin^{2} (u) (1 + cot^{2} (u)) = 1

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

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

prove tan(x)+cot(x)=(csc(x))/(cos(x))prove

tan (x) + cot (x) = \frac{csc ( x )}{cos ( x )}

prove sec(θ)-tan(θ)sin(θ)=cos(θ)prove

sec (θ) - tan (θ) sin (θ) = cos (θ)

prove csc(θ)= 1/(cos(θ))prove

csc (θ) = \frac{1}{cos ( θ )}
