expand x(xcos(x)+2sin(x))

expand

x (x cos (x) + 2 sin (x))

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

Solution steps

x (x cos (x) + 2 sin (x))

Apply the distributive law:

a (b + c) = ab + a c

x (x cos (x) + 2 sin (x)) = xx cos (x) + x \cdot 2 sin (x)

= xx cos (x) + x \cdot 2 sin (x)

Simplify

xx cos (x) + x \cdot 2 sin (x) : x^{2} cos (x) + 2 x sin (x)

= x^{2} cos (x) + 2 x sin (x)

(x - x + 1) (x + 1)

(2 + y)^{12}

\frac{s ( 3 s + 5 )}{s ^{2} + s - 2}
