The length of a rectangle is 5t+6 and its height is t^6 , where t is time in seconds and the dimensions are in inches. find the rate of change of area, a, with respect to time

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

What is the rest of the question?
