expand (x-pi)(1-cos(x))

expand

(x - π) (1 - cos (x))

x - x cos (x) - π + π cos (x)

Solution steps

(x - π) (1 - cos (x))

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = x, b = - π, c = 1, d = - cos (x)

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

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

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

Simplify

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

= x - x cos (x) - π + π cos (x)
