Related to this QuestionFind the unit tangent vector to the curve given by r(t) = \cos^2 t i + \sin^2 t j Define the curve C by the parametric equations x = sin pi t, y = square root{t}, z = cos pi t. a. Find the unit tangent vector T...
We know that a parametric curve always contains a third variable that is t with two main variables that are x and y. Now, since the slope of a tangent line on the parametric curve is dydx, so to find it, first, we differentiate both x and ...
Thus, the tangent line is parallel to the vector (-1,1,-1) and parametric equations are x=1+(-1)t=1-t, y=0+1⋅ t=t, z=1+(-1)t=1-t.反馈 收藏
