R dr d theta
WebThis is what I learned on this video and just want to verify if they're correct. 1) Calculating y' in terms of theta will give you the rate of change of the y-value as theta changes, 2) Calculating x' in terms of theta will give you the rate of change of the x-value as theta changes, and. 3) The rate of change of y with respect to x will give ... WebAnswer (1 of 2): By looking at the equation, we can see that this is simply a first order differential equation. There are a few ways to solve this. I will show two of them. Since our …
