Hence 1t is the slope of tangent at point P t. Use t as the parametrized variable You can put this solution on YOUR website. The slope of a line having a parametric equation is -3.
This is a valid way for parametric equations endgroup lab bhattacharjee Dec 6 13 at 419 begingroup My only other question just to make sure I am doing it.
Consider the plane curve defined by the parametric equations beginalign xt 2t3 labeleq1 yt 3t4 labeleq2 endalign within 2t3. But we actually want to do some calculus in particular we wanna find the derivative we wanna find the derivative of y with respect to x the derivative of y with respect to x when t when t is equal to negative one third. But the goal in this video isnt just to appreciate the coolness of graphs or curves defined by parametric equations. Consider a line passing through the point A x 1 y 1 and making an.
