Answer 2

It seems like you've provided two parametric equations for x and y in terms of a parameter t. Let's break down these equations:

1. $X = 3(\sin t - t \cos t)$
2. $Y = 3(\cos t + t \sin t)$

These equations define a parametric curve in the xy-plane as t varies over a certain range. To better understand the curve, we can analyze its behavior for different values of t.

Let's first examine the behavior of X and Y for various values of t:

• As t varies, $\sin t$ and $\cos t$ change, which means X and Y will also change accordingly.
• The factor of 3 in front of both $\sin t - t \cos t$ and $\cos t + t \sin t$ simply scales the curve but does not change its shape.

To visualize the curve more effectively, you can plot X and Y for a range of values of t. Depending on the specific range of t you choose, you will obtain a portion of the curve.

Please specify the range of values for t, and I can help you plot the curve or provide more specific information about its behavior within that range.
