expand (x^2+3)e^5x-cos(2x)e^6x

expand

(x^{2} + 3) e^{5} x - cos (2 x) e^{6} x

e^{5} x^{3} + 3 e^{5} x - cos (2 x) e^{6} x

Solution steps

(x^{2} + 3) e^{5} x - cos (2 x) e^{6} x

= e^{5} x (x^{2} + 3) - e^{6} x cos (2 x)

Expand

e^{5} x (x^{2} + 3) : e^{5} x^{3} + 3 e^{5} x

= e^{5} x^{3} + 3 e^{5} x - cos (2 x) e^{6} x

\frac{9 x + 18 + x ^{2}}{x ^{2} ( x + 2 )}

\frac{s - 2}{( s ^{2} + 6 s + 13 ) ^{2}}

(- e^{- t} cos (4 t) - 4 e^{- t} sin (4 t))^{2}

\frac{1380 ( - x ^{2} + 32 )}{( x ^{2} + 32 ) ^{2}}

3 i^{40} - 5 i^{15} - i^{8}
