Please make sure each step must logically follow from the previous one and every claim must be justified.

1. Consider the function f(a) = =(23) 4 2-5 + (Vx4) (e-Inx) - sin(x) a) (1 point) Simplify the expression for f. Clearly show all your steps. b) (2 points) Find an antiderivative of f such that this antiderivative F satisfies F(0) = 1
