$\frac{\cos\left(a\right)}{\cot\left(a\right)}$
Learn how to solve proving trigonometric identities problems step by step online. Prove the trigonometric identity cos(a)/cot(a)=sin(a). Starting from the left-hand side (LHS) of the identity. Applying the trigonometric identity: \cot\left(\theta \right) = \frac{\cos\left(\theta \right)}{\sin\left(\theta \right)}. Divide fractions \frac{\cos\left(a\right)}{\frac{\cos\left(a\right)}{\sin\left(a\right)}} with Keep, Change, Flip: a\div \frac{b}{c}=\frac{a}{1}\div\frac{b}{c}=\frac{a}{1}\times\frac{c}{b}=\frac{a\cdot c}{b}. Simplify the fraction \frac{\cos\left(a\right)\sin\left(a\right)}{\cos\left(a\right)} by \cos\left(a\right).
