i Dont know how to apprach these questions,
need to find the normals and tangents of the following parabolas at certain points.
please show working
y^2=2(x-3) at point (5,2)
x-cos2theta, y=costheta at point where theta=pi/4
y=(x-2)^2 at point (3,1)
x=cos2t, y=sint at point where t=0
x=t+3, y=t^2-5 at point where t=1
(y-2)^2=4(x-1) at the vertex.
thanks.
