expand-cos(x)(1-x)

Solution

expand

- cos (x) (1 - x)

Solution

- cos (x) + x cos (x)

Solution steps

- 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)
