Find all points on the curve that have the given slope. x = 2cost, y= 8sint, slope =-1

,

,

Step-by-step explanation:

In the case of parametric equations, the slope of the curve is equal to:

Where and are the first derivatives of and regarding . Let be and , their first derivatives are found:

and

Thus, equation for the slope is:

If , then:

Tangent is positive at 1st quadrant and is a function with a periodicity of , the set of solutions are:

,
