Which of the following strategies could be used to prove the equation below in two steps, including simplification?sin^2 x cot^2 x=cos^2 x

The equation is given
[tex]sin^2xcot^2x=cos^2x[/tex]To prove LHS equal to RHS,
Write the expression in terms of sine and cosine.
[tex]\begin{gathered} sin^2x\frac{cos^2x}{sin^2x}=cos^2x \\ cos^2x=cos^2x \end{gathered}[/tex]Hence the correct option is B.
