expand cos((t^2)(s-2t))(2s)

expand

cos ((t^{2}) (s - 2 t)) (2 s)

2 s cos (t^{2} s - 2 t^{3})

Solution steps

cos ((t^{2}) (s - 2 t)) (2 s)

Remove parentheses:

(a) = a

= cos (t^{2} (s - 2 t)) \cdot 2 s

Expand

t^{2} (s - 2 t) : t^{2} s - 2 t^{3}

= 2 s cos (- 2 t^{3} + t^{2} s)

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

\frac{1}{s ( s - a )}

\frac{4 ( - 1 ) ^{n + 1} n - 8 n + ( - 1 ) ^{n} - 1}{4}

(2 x + 4 y) + (2 x - y) \frac{d y}{d x}

\frac{2 ( 8 2 - 2 )}{5}
