Simplify the expression: <br> sin^4x cosx/ cos^4x sinx
netineya [11]

Answer:

tan^3x

Step-by-step explanation:

We want to simplify:

\frac{\sin^4x\cos x}{\cos^4x\sin x}

This is the same as:

\frac{\sin^3x \sin x\cos x}{\cos^3x \cos x\sin x}

Cancel out the common factors to get;

\frac{\sin^3x}{\cos^3x}

This is the same as

(\frac{\sin x}{\cos x} )^3=tan^3x
