expand (t+1)cos(2t)

Solution

expand

(t + 1) cos (2 t)

Solution

t cos (2 t) + cos (2 t)

Solution steps

(t + 1) cos (2 t)

= cos (2 t) (t + 1)

Apply the distributive law:

a (b + c) = ab + a c

cos (2 t) (t + 1) = cos (2 t) t + cos (2 t) \cdot 1

= cos (2 t) t + cos (2 t) \cdot 1

Simplify

cos (2 t) t + cos (2 t) \cdot 1 : t cos (2 t) + cos (2 t)

= t cos (2 t) + cos (2 t)
