[10 points ] 12. (a) Find dy / dx and day / dx2 as functions of t for the curve whose parametric equations are: x = 12+1 y = 12 +t Simplify your answers as much as possible. (b) Find the slope-intercept equation in Cartesian coordinates for the line tangent to the curve in part (a) at the point corresponding to t = 2. [4 points ] 13. Let P be the point represented by the polar coordinates (4, 5nt / 3). Find the exact rectangular coordinates x and y of P. I do not want decimal approximations
