Find du/dt for the following functions:
Solution:
Consider the given equation above
Since the first function has three variables, then we have to take the partial derivatives of a function with respect to x and y as follows
Next, take the derivative of the other functions with respect to x since they have only one variables as follows
Therefore,
Substitute the values of x and y in the above equation to obtain the final equation in terms of u and t as follows
