Solve tg(p/2 a)-ctg(2p-a)

Evaluate

t g (\frac{p}{2} a) - c t g (2 p - a)

Remove the parentheses

t g \times \frac{p}{2} a - c t g (2 p - a)

Multiply the terms

More Steps

\frac{t g p a}{2} - c t g (2 p - a)

Expand the expression

More Steps

\frac{t g p a}{2} - 2 c t g p + c t g a

Reduce fractions to a common denominator

\frac{t g p a}{2} - \frac{2 c t g p \times 2}{2} + \frac{c t g a \times 2}{2}

Write all numerators above the common denominator

\frac{t g p a - 2 c t g p \times 2 + c t g a \times 2}{2}

Multiply the terms

\frac{t g p a - 4 c t g p + c t g a \times 2}{2}

Solution

\frac{t g p a - 4 c t g p + 2 c t g a}{2}
