The vector equation for the curve is r(t)=(e^(-t)cos t,e^(-t)sin t,e^(-t)), so (split)r'(t)&=(e^(-t)(-sin t)+(cos t)(-e^(-t)), e^(-t)cos t+(sin t)(-e^(-t)), (-e^(-t))) &=(-e^(-t)(cos t+sin t), e^(-t)(cos t-sin 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 ...
By using the ratio dy/dtdx/dt, find the slope of the tangent line to the graph of the function y=u(x) at t=π6, if the parametric equations for the function u(x) are given by: x(t)=sec(t),y(t)=tan...
Find the slope of the tangent line to the curve with parametric equations: x=∫0t1+udu, y=1+2t−t2 at the point (0,1). Derivatives: Recall that a derivative tells us the slope of a function at a point. When we have a set...
This function has real values for x⩾0. It is differentiable for all positive values ofx, but the limit does not exist at x=0, so it is not differentiable at x=0. The tangent to the curve at x=0 is vertical. Exercise 6.2 Decide where the following functions are differentiable: (a...
definition: (##M## denotes a manifold structure, ##U## are subsets of the manifold and ##\phi## the transition functions) Def: A smooth curve in ##M## is a map ##\gamma: I \rightarrow M,## where ##I \subset \mathbb{R}## is an open interval, such that for any chart.....
The formula for this addition is thus the same as for addition of functions, (V+W)(p)=V(p)+W(p). This scheme occurs over and over again. We shall call it the pointwise principle: If a certain operation can be performed on the values of two functions at each point, then that ...
