The unit normal vector to the surface, {eq}f\left( {x,y,z} \right) = 0 {/eq} at the point {eq}\left( {a,b,c} \right) {/eq} is a vector obtained by dividing the gradient of {eq}f\left( {x,y,z} \right) {/eq} at the point {eq}\...
Find a normal vector at point(−1,0)on a level curve corresponding tof(x,y)=1. Level Curves: Recall that a level curve is a slice across a surface. When we have a surface described byz=f(x,y), then level curves are horizontal slices in plan...
Find the unit tangent vector T(t) at the point with the given value of the parameter t. r(t)=cos t i+3 t j+2 sin 2 t k, t=0 相关知识点: 试题来源: 解析 r'(t)=-sin t i+3 j+4 cos 2 t k ⇒ r'(0)=3 j+4 k. Thus T(0)=( r'(0))(| r'(0)|)=1(√...
