Example 3.4 Find the directional derivative of g(x, y) = ex2cos y at (1, π)in the direction −3i + 4j.
Question
Solution 1
Sure, here are the steps to find the directional derivative:
Step 1: Compute the gradient of g(x, y) = e^(x^2)cos(y)
The gradient of a function is a vector that contains the first derivative of the function with respect to each variable. In this case, we have two variables, x and y.
