How do I maintain the information learned from homework (trigonometry)? I frequently forget most of the subject topic for the test, it is not the actual problem-solving but the actual answering method. It is a dual enrollment class at LSU where the answer has to be exact. On top of learning math you must learn the way to answer the math in the exact way, zero room for error.

Verify the identity.

cot x = \frac{s i n 2 x}{1 - c o s 2 x}

Use the appropriate double-angle formulas to rewrite the numerator and denominator simplified.

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

Simplify the denominator. Enter the numerator found in the previous step. The expression from the previous step then simplifies to cot
