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

expand

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

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

Solution steps

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

Expand

l (1 - cos (t)) : l - l cos (t)

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

Apply the fraction rule:

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

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

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

e^{x (x - 5)}

(10 e^{t} + 4) (t^{4} + 1)

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

\frac{2 s ^{2} - 9 s - 35}{( s + 1 ) ( s - 2 ) ( s + 3 )}

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