Unit Tangent Vector: We can find the unit tangent vector of a curve using the formula {eq}T\left( t \right) = \frac{{r'\left( t \right)}}{{\left\| {r'\left( t \right)} \right\|}} {/eq}. Suppose we have a vector function {eq}r\left( t ...
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(√...

解析 f(x,y)=xy\ ⇒ \ ∇ f(x,y)= y,x, ∇ f(3,2)=2,3. ∇ f(3,2) is perpendicular to the tangent line, so the tangent line has equation ∇ f(3,2)⋅ x-3,y-2=0⇒ 2,3⋅ x-3,x-2=0⇒ 2(x-3)+3(y-2)=0 or 2x+3y=12....
at the given point (5,25). Unit Vector:To find a unit vector parallel to the tangent line to a given function parabola in this case we find the derivative of the function. Then we find the its value at the given point. Then we relate the coordinates of...
