Please help me for part c how to do part c of this questions The equation h = 7 cos (pi/3 t) models the height h in centimeters after t seconds of a weight attached to the end of a spring that has been stretched and then released. a. Solve the equation for t. b. Find the times at which the weight is first at a height of 1 cm, of 3 cm, and of 5 cm above the rest position. Round your answers to the nearest hundredth. c. Find the times at which the weight is at a height of 1 cm, of 3 cm, and of 5 cm below the rest position for the second time. Round your answers to the nearest hundredth.

In your shoes one of the first things I'd do would be to graph the given function on the interval [0, 10]. such a graph would enable you to estimate the required times. Then I'd use trig to calculate those times more accurately.

\[-\frac{ 1 }{ 7 }=\cos \left( \frac{ \pi }{ 3 } \right)t,\frac{ 1 }{ 7}=\cos \left( \pi- \frac{ \pi }{ 3 }\right)t\] and \[\frac{ 1 }{ 7 }=\cos \left( \pi+\frac{ \pi }{ 3 } \right)t\] solve as usual
