Hi, Everyone,
I have the following problem. Given function is g (s, t) = s ^ 2 * exp (t). Find directional derivative of the function at the point (2,0) in direction of vector v = i + j. The book says to find del g with respect to s and t and dot it with normalized v. But I disagree because g is a function of s and t (not x and y) whereas v is defined as i + j. Can somebody help?
Thank you
