Section 9.2: Problem 2 (1 point) Find the equation for the line tangent to the parametric curve: = 8-4t = 4+2 - +4 at the points where t = 2 and t = -2. Fort = 2, the tangent line (in form y = mc + b) is Fort = - -2 , the tangent line is ySection 9.2: Problem 3 (1 point) (a) Find dy dr expressed as a function of t for the given the parametric equations: = 2t + Int = 7t - Int dy dx (b) Find d' y da-2 expressed as a function of t. dx2Section 9.2: Problem 4 (1 point) Consider the parametric curve: I 25 - +2 y = +- 9t At which t value(s) is the tangent to this curve vertical? ( Note: If there is more than one write them as a comma separated list) t = Write the point(s) at which the tangent is vertical.( Note: If there is more than one write them as a comma separated list, e.g. (1,2),(3,4)) At which t value(s) is the tangent to this curve horizontal? ( Note: If there is more than one write them as a comma separated list). t = Write the point(s) at which the tangent is horizontal.( Note: If there is more than one write them as a comma separated list, e.g. (1,2),(3,4)) Use a graphing device to graph the curve and check your work.Section 9.2: Problem 5 [1 point] You are given the parametric equations 3 = 2t; + 31'!2 12, y = 25' l 3112 + 1. (a) List all of the points (my) where the tangent line is horizontal. In entering your answer, list the points starting with the smallest value of z. lftwo or more points share the same value of 2, list those points starting with the smallest value of 19. It any blanks are unused, type an uppercase "N" in them. Paint 1: (my) = DD) Point 2: (my) = DD) Paint 3: (my) 2 DD} (b) List all of the points (my) where the tangent line is vertical. In entering your answer, list the points starting with the smallest value of I. If two or more points share the same value of 5:, list those points starting with the smallest value of g. It any blanks are unused, type an uppercase "N" in them. Paint 1: (my) = DD) Point 2: (my) = DD) Paint 3: (my) 2 DD)
