TT To find the slope and concavity at the given value of the parameter, you need to compute dy dạy and at 8 = dx dx2 4 The slope is coles = -cot e dy dx le = 4 TT A 4 To determine concavity, we compute the following. 1 3 dạy dx2 le = 쁽 - cscole 1 = 4 4 =
Convert the polar equation to rectangular form and sketch its graph. r = 9 cot(0) csc(O) Step 1 The polar coordinates (r, 0) of a point are related to the rectangular coordinates (x, y) of the point as follows. X=r y = r
