Answer to: Find the unit tangent vector to the curve at the specified value of the parameter. r (t) = 8 t vector i + 9 t^2 vector j at t = 1. By...
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...
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
Now, since the slope of a tangent line on the parametric curve is {eq}\dfrac{dy}{dx} {/eq}, so to find it, first, we differentiate both {eq}x {/eq} and {eq}y {/eq} with respect to {eq}t {/eq} and then divide {eq}\dfrac{dy}{d...
A unit vector in physics is an object that has a magnitude of 1. They are used to represent a direction. How do you write unit vectors? Any vector has a corresponding unit vector. The unit vector can be written as the vector divided by its magnitude. How do you find the unit vector...
