1)What is the position vector r(t) as a function of angle $\theta \left(t\right)$. For later remember that $\theta \left(t\right)$ is itself a function of time.

Give your answer in terms of $R,\theta \left(t\right)$, and unit vectors x and y corresponding to the coordinate system in thefigure. 2)For uniform circular motion, find $\theta \left(t\right)$ at an arbitrary time t.

Give your answer in terms of $\omega$ and t.

3)Find r, a position vector at time.

Give your answer in terms of R and unit vectors x and/or y.

4)Determine an expression for the positionvector of a particle that starts on the positive y axis at (i.e., at ,$({x}_{0},{y}_{0})=(0,R)$) and subsequently moves with constant $\omega$.

Express your answer in terms of R, $\omega $ ,t ,and unit vectors x and

where x is in radians.

a) Use a graphing utility to graph the arctangent function and its polynomial approximation in the same viewing window. How do the graphs compare?

b) Study the pattern in the polynomial approximation of the arctangent function and predict the next term. Then repeat part (a). How does the accuracy of the approximation change when an additional term is added?

The students today that are looking for Calculus problems and answers online have way more luck than they would have even a few decades ago. However, one thing stays in common: it is not enough to find your answers and write them down for equations or trigonometry problems. It takes time to learn these rules, which is why Calculus and Analysis are so complex for most people. Do not let Calculus become another nightmare for you because you can look through the questions and answers and learn by example.
