expand (sin(x)+xcos(x))(3cos(xsin(x)))

expand

(sin (x) + x cos (x)) (3 cos (x sin (x)))

3 cos (x sin (x)) sin (x) + 3 x cos (x sin (x)) cos (x)

Solution steps

(sin (x) + x cos (x)) (3 cos (x sin (x)))

= (3 cos (x sin (x))) (sin (x) + x cos (x))

Apply the distributive law:

a (b + c) = ab + a c

(3 cos (x sin (x))) (sin (x) + x cos (x)) = 3 cos (x sin (x)) sin (x) + 3 cos (x sin (x)) x cos (x)

= 3 cos (x sin (x)) sin (x) + 3 cos (x sin (x)) x cos (x)

= 3 cos (x sin (x)) sin (x) + 3 x cos (x sin (x)) cos (x)

\frac{4 x ^{2}}{( x - 5 ) ^{2} ( x + 5 ) ^{2}}

(\frac{x y ^{2}}{2} = \frac{y}{x} + c) \cdot 2

22 (7 + 33)

\frac{1}{( x - 2 ) ( x ^{2} + 4 )}

(cos (x)) (cos (x) - sin (x))
