expand ((1-cosh(x))^2)/h

Solution

expand

\frac{( 1 - cosh ( x ) ) ^{2}}{h}

Solution

\frac{1}{h} - \frac{2 cosh ( x )}{h} + \frac{cosh ^{2} ( x )}{h}

Solution steps

\frac{( 1 - cosh ( x ) ) ^{2}}{h}

(1 - cosh (x))^{2} = 1 - 2 cosh (x) + cosh^{2} (x)

= \frac{1 - 2 cosh ( x ) + cosh ^{2} ( x )}{h}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{1 - 2 cosh ( x ) + cosh ^{2} ( x )}{h} = \frac{1}{h} - \frac{2 cosh ( x )}{h} + \frac{cosh ^{2} ( x )}{h}

= \frac{1}{h} - \frac{2 cosh ( x )}{h} + \frac{cosh ^{2} ( x )}{h}
