To help find the velocity of particles requires the evaluation of the indefinite integral of the acceleration function, a(t), with respect to time, t, i.e. v = [ a(t)dt. Evaluate the following indefinite integrals. Check your value for each integral by differentiating your answer. (a) 5t (8 cos 2t64 sin 4t + 27e¯³t)dt; (b) √(324t5 - 54t² + 5)(Int)² dt;
