Minimum velocity

Image
0 $begingroup$ There is a particle moving along the $x$ -axis at any time $t geq 0$ . The velocity of this particle is given by $$v(t) = cos(πt) - t(6-2pi).$$ I am supposed to find the particle's minimum velocity over the interval $[0,2]$ . I found the derivative of this velocity function and set it equal to zero, but I am having trouble with getting the right answer. I used the option on my calculator to find the min, but I can’t seen to find it using calculus. Help is greatly appreciated! calculus derivatives share | cite | improve this question edited Jan 16 at 4:16 AEngineer 1,5...
