 Question 437606: For the parametric equation x=7cost, y=sint, 0Answer by stanbon(57384)   (Show Source): You can put this solution on YOUR website!For the parametric equation x=7cost, y=sint, 0 find the coordinates of at least 5 points, graph the curve and indicate the direction of the increasing t. ---------------------------- If t = 0, 7cos(0) = 7; sin(0) = 0 --- If t = 30, 7cos(30) = (7/2)sqrt(3); sin(30) = 1/2 ----- If t = 150, 7cos(30) = -(7/2)sqrt(3); sin(150) = 1/2 --- If t = 210, 7cos(210) = -(7/2)sqrt(3); sin(150) = -1/2 ---- If t = 330, 7cos(330) = (7/2)sqrt(3) ; sin(330) = -1/2 ============================================================ cheers, Stan H. =============
