$\frac{\frac{1-\cos\left(a\right)}{\sin\left(a\right)}}{\sin\left(a\right)\left(1-\cos\left(a\right)\right)}$
Learn how to solve simplification of algebraic expressions problems step by step online. Simplify the expression (((1-cos(a))/sin(a))/sin(a))/(1-cos(a)). Divide fractions \frac{\frac{\frac{1-\cos\left(a\right)}{\sin\left(a\right)}}{\sin\left(a\right)}}{1-\cos\left(a\right)} with Keep, Change, Flip: \frac{a}{b}\div c=\frac{a}{b}\div\frac{c}{1}=\frac{a}{b}\times\frac{1}{c}=\frac{a}{b\cdot c}. Divide fractions \frac{\frac{1-\cos\left(a\right)}{\sin\left(a\right)}}{\sin\left(a\right)\left(1-\cos\left(a\right)\right)} with Keep, Change, Flip: \frac{a}{b}\div c=\frac{a}{b}\div\frac{c}{1}=\frac{a}{b}\times\frac{1}{c}=\frac{a}{b\cdot c}. Simplify the fraction \frac{1-\cos\left(a\right)}{\sin\left(a\right)^2\left(1-\cos\left(a\right)\right)} by 1-\cos\left(a\right). Applying the cosecant identity: \displaystyle\csc\left(\theta\right)=\frac{1}{\sin\left(\theta\right)}.
