You're given the parametric equation of a curve:

$\displaystyle

x(t) = t^b\cos(2\pit)

y(t) = t^b/sin(2\pit)

$

Find the slope of the graph when t > 0.

$\displaystyle

x'(t) = (t^b)(-\sin(2\pit))(2\pi) + (cos(2\pit))(bt^(b-1))

y'(t) = (t^b)(2\picos(2\pit)) + (sin(s\pit))(bt^(b-1))

$

Can anyone direct me to the thread that teaches you how to use LATEX??
