ACTIVITY 3 Solve the ff. problems. Show all your solutions. 1 ) Given the set of parametric equations x = 2t' - 1 and y = 3+ + 4 eliminate the parameter t and describe the graph of the resulting equation. 2 ) Given that x = 13 + t and 4 = 3 t + t 2 2 find dy dy d'y dx and d'y dy 2 dx 3 dx 4 3) Find the equations of the lines tangent and normal to the curve given by the para- metric equations x = 4 cost and y = 2sin?t at t = I 4 ) Describe the graph of the given set C = f ( x,y ): x = ti, y=vi-ty
