- Homework Statement
- Find the derivative dy/dx of the curve (circle) expressed in parametric form: (x,y)=(cos t, sin t).
- Relevant Equations
- dy/dx of (x(t), y(t))= y'(t)/x'(t)
y'(t)/x'(t) = cos t/-sin t = -cot t.
But as t is the angle, and the derivative is the slope, then isn't the slope supposed to be tan t?
