3 . Consider a curve define parametrically as x(t) = 3 - t-1 and y(t) = 2t + t-1 a. Write the equation of the curve in non-parametric form (i.e. eliminate t between the two equations.) b. Find dy/dx in terms of t using parametric differentiation. C. Find day/ dx2 in terms of t using parametric differentiation. d. Find the equation of the tangent line to the curve when t = 1.
