expand (1+x)cos(x)

Solution

expand

(1 + x) cos (x)

Solution

cos (x) + x cos (x)

Solution steps

(1 + x) cos (x)

= cos (x) (1 + x)

Apply the distributive law:

a (b + c) = ab + a c

cos (x) (1 + x) = cos (x) \cdot 1 + cos (x) x

= cos (x) \cdot 1 + cos (x) x

Simplify

cos (x) \cdot 1 + cos (x) x : cos (x) + x cos (x)

= cos (x) + x cos (x)
