expand tcos(wt)u(t^2-1)

expand

t \cdot cos (wt) \cdot u (t^{2} - 1)

t^{3} u cos (wt) - t u cos (wt)

Solution steps

t cos (wt) u (t^{2} - 1)

= t u cos (wt) (t^{2} - 1)

Apply the distributive law:

a (b - c) = ab - a c

t u cos (wt) (t^{2} - 1) = t u cos (wt) t^{2} - t u cos (wt) \cdot 1

= t u cos (wt) t^{2} - t u cos (wt) \cdot 1

Simplify

t u cos (wt) t^{2} - t u cos (wt) \cdot 1 : t^{3} u cos (wt) - t u cos (wt)

= t^{3} u cos (wt) - t u cos (wt)
