Calculus 3: Vector Functions

The position of a particle in the xy plane at time t is r(t)=(t+1)i+(t21)j\vec{r}(t) = (t+1)\mathbf{i} \, + \, (t^2-1)\mathbf{j} Find an equation in x and y whose graph is the path of the particle. Then find the particle's velocity and acceleration vectors at t = 1.

Evaluate the function f at T = 0 and S = π\pi and determine the resulting point in three-dimensional space.

Using vector valued functions, describe the path of a particle or object, taking into account time as a variable.

Parametrize the same curve using different rates and understand the derivative of a position vector valued function.

Describe the path of a particle in three-dimensional space using vector valued functions.

Given the vector-valued function r(t)=t,3cos(t),5sin(t)r(t) = \langle t, 3\cos(t), 5\sin(t) \rangle, describe the curve in 3D space.

Given the vector-valued function r(t)=2cos(t),2sin(t),6et/4r(t) = \langle 2\cos(t), 2\sin(t), 6e^{-t/4} \rangle, analyze how the curve behaves in 3D space and the effect of exponential decay in the zz-component.

Give an example of a vector-valued function r(t) and determine its domain and range in R3R^3.

Visualize a vector-valued function and analyze its behavior as it does not intersect itself within a given domain subset from t=5t = 5 to t=20t = 20.
