Question

finding derivatives of polar coordinates

Answer 1

is there an equations?

Answer 2

x=2cosT y=sinT T=Pi/4

Answer 3

so take the derivative of both with respect to T

Answer 4

question is fint the equation of the line tangent to the curve by given value

Answer 5

ok so to find M you take the derivative of both functions first then do (Dx/dt)/(dy/dt) which would give u ur Slope equation then plug in Pi/4 for Theta. once get that plug in theta into the x and y funcitons to get ur x and y and then use y-y1=m(x-x1) equation to find tangent line. does that help?

Answer 6

bingo thanks!

Answer 7

no problem!!
