Question

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 3 sin πt + 2 cos πt, where t is measured in seconds. (Round your answers to two decimal places.)

Answer 1

All you need to do is substitute a number in as t so if it was at 4s you would put 4 in as t and s would show the displacement at that specific time
