expand (2(1-cos(t)))/t

expand

\frac{2 ( 1 - cos ( t ) )}{t}

\frac{2}{t} - \frac{2 cos ( t )}{t}

Solution steps

\frac{2 ( 1 - cos ( t ) )}{t}

Expand

2 (1 - cos (t)) : 2 - 2 cos (t)

= \frac{2 - 2 cos ( t )}{t}

Apply the fraction rule:

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

\frac{2 - 2 cos ( t )}{t} = \frac{2}{t} - \frac{2 cos ( t )}{t}

= \frac{2}{t} - \frac{2 cos ( t )}{t}

(2 x + 3)^{2}

(1 - i)^{9}

(2 - 2 i)^{5}

(3 + 3 sin (x))^{2}

\frac{2 x + 3}{( x - 1 ) ( x ^{2} + 4 )}
