expand cos(x)(x-1)

Solution

expand

cos (x) (x - 1)

Solution

x cos (x) - cos (x)

Solution steps

cos (x) (x - 1)

Apply the distributive law:

a (b - c) = ab - a c

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

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

Simplify

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

= x cos (x) - cos (x)
