Hi, I am in difficulty when I kept trying to do these questions.

Could you give me a help to solve these questions?

Thank you so much.

Q1:

Consider the curve in the plane T (t) = (t - sint)i + (1 - cost)j. Find all values of t for which there is a maximum or minimum value for | |, as well as the values of t for which there is a maximum or minimum value for | |all. Note: This curve forms something called a cycloid. You can play around with the curves graphically by dragging the slider labeled 'b' at this DESMOS link: https://www.desmos.com/calculator/a3rrul40yw
