the derivative of sine theta

over

the derivative of cosine theta?

**bobpursley**, Wednesday, December 2, 2009 at 2:52pmI think you are greatly confused.

The slope of any line at an angle theta from the reference line is equal to tangent theta.

tangenttheta is NOT equal to derivative of sin over the derivative of cosine.

Why is slope equal to tangent?

slope is defined as deltaY/deltax where x is the reference point for the angle. but deltaY/deltaX is by definition the tangent of the central angle, theta.
