Recall from the Introduction to Derivatives that the derivative at a point can be interpreted as the slope of the tangent line to the graph at that point. In the case of a vector-valued function, the derivative
For example, we invoke the pointwise principle to extend the operation of scalar multiplication (on the tangent spaces of R3). If f is a real-valued function on R3 and V is a vector field on R3, then fV is defined to be the vector field on R3 such that (fV)(p)=f(p)V(p) ...
A tangent vector field v on Rn is a function v that associates to every point p∈Rn a tangent vector to Rn based at p, i.e., a tangent vector vp∈TpRn. From: Differential Forms (Second Edition), 2014 About this pageSet alert Discover other topics ...
To find the unit tangent vector of a vector-valued function {eq}\vec{r}(t) {/eq} we find the derivative of the given function and its magnitude and apply the formula: $$\mathbf{\vec{T}(t)}=\dfrac{\mathbf{\vec{r}^...

Find an equation of the tangent plane to the surface represented by the vector-valued function at the given point. {eq}r(u,v) = ui + vj + \sqrt{(uv)}k, (1,1,1) {/eq} Equation of the Tangent: The equation of the tangent is determined by taking...
The curve can be specified as a free or position Vector or a Vector valued procedure. This determines the returned object type. • If t is not specified, the function tries to determine a suitable variable name by using the components of C. To do this, it checks all of the indetermin...
If f is a Vector or Vector-valued procedure, var1 and var2 must specify the names of the two parameters of the surface. • If f is a Vector or a scalar expression, the output is a position Vector. If f is a procedure, the output is a procedure that evaluates to a position Vec...
In mathematics, the tangent space of a manifold facilitates the generalization of vectors from affine spaces to general manifolds, since in the latter case one cannot simply subtract two points to obtain a vector pointing from one to the other....
