expand x(xcos(x)+2xsin(x))

expand

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

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

Solution steps

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

Apply the distributive law:

a (b + c) = ab + a c

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

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

Simplify

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

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

\frac{x}{( 1 + 3 x ) ^{2}}

(1 + x)^{\frac{- 1}{5}}

(x + y + z = 0,) (3 x - y + z = - 42)

\frac{( x - 1 ) ln ( x - 1 )}{x}

(1 - x^{2})^{3}
