I have an assignment to do in Maplesoft, I am not sure how to do some of the questions. Here's one for example.
The position of a particle in space at any time t > 0 (in seconds) is given by
x(t) = 22. 5 e^t, y(t) = 16 cosh(3t), z(t) = 4 sinh(2t) (in meters).
(a) Use the commands diff and fsolve to find the time t when the particle first reach
the speed of 190 m/s.
(b) Use the command eval to find the initial speed of the particle.
anyone got any ideas? I am not sure how to enter it in. Thanks.
