f(x) = (x-1) ^ 2

would the x-int be 1? and how do you figure out the y-int? and should the turning point be 1 as well? since the degree in this equation is 2 and you subtract 1 from the highest exponent. thanks for the help.

Hi, I'm a math student. I'm having trouble with this problem. If someone could help explain the problem, I'd really appreciate it. The answers are given below.

Find the expression for the unit vector tangential to the curve given in cylindrical coordinates by (r^2)sin [2(phi)] = 1, z = 0. Then obtain the unit vectors tangential to the curve at the points: a) (1, pi/4, pi/2) b) (1, pi/2, pi)

Answer: +-(cos 2(phi) ar - sin 2(phi) ap); a) +-ap; b) +-((3^(1/2))/2 ar - (1/2) ap))
Thank You

Note: ar = unit vector of in radial direction. ap = unit vector in phi direction. +- means plus or minus
