Find a Cartesian equation relating and y corresponding to the parametric equations x = 4t 1+t³ y = 3t² 1+t³ t-1 Write your answer in the form P(x, y): = 0 where P(x, y) is a polynomial in x and y such that the coefficient of ³ is 27. Answer: 27x^3+64y^3-144xy = 0 Find the equation of the tangent line to the curve at the point corresponding to t = 1. Answer: y =
