expand sin(t)cos(10(t-r))

expand

sin (t) cos (10 (t - r))

cos (10 t - 10 r) sin (t)

Solution steps

sin (t) cos (10 (t - r))

Expand

10 (t - r) : 10 t - 10 r

= cos (10 t - 10 r) sin (t)

(2 x + \frac{1}{x})^{12}

\frac{1}{s ( 1 - e ^{- s} )}

\frac{7 s + 2}{( s + 2 ) ( s - 1 ) ( s - 2 )}

(\frac{3 x ^{2}}{2 y} + \frac{z}{6}) (\frac{3 x ^{2}}{2 y} - \frac{z}{6})
