expand ((scos(t))+(t))(scos(t))

expand

((s cos (t)) + (t)) (s cos (t))

s^{2} cos^{2} (t) + s t cos (t)

Solution steps

((s cos (t)) + (t)) (s cos (t))

Simplify

(s cos (t)) + (t) : s cos (t) + t

= (s cos (t) + t) s cos (t)

= s cos (t) (s cos (t) + t)

Apply the distributive law:

a (b + c) = ab + a c

s cos (t) (s cos (t) + t) = s cos (t) s cos (t) + s cos (t) t

= s cos (t) s cos (t) + s cos (t) t

Simplify

s cos (t) s cos (t) + s cos (t) t : s^{2} cos^{2} (t) + s t cos (t)

= s^{2} cos^{2} (t) + s t cos (t)
