2. Consider the curver = 30 + 4sine. a) Write expressions for the x and y coordinates of the curve at the angle 0. Find the coordinates when 0 = -". (3 pts.) b) Find the values of and dy do when 0 = 7. What do these tell us about the curve at that point? (3 pts.) c) Find the value of -or when 0 = . What does it tell us about the curve at that point? (3 pts.) d) Find the value of - do when 0 = T. What does it tell us about the curve at that point? (2 pts.) e) For what value(s) of 0 on the interval ,
