Consider the function f(x,y)=∜(x^2+y^2 ) Find the gradient vector of the function at the point (1, 1). Find the equation of the tangent plane at the point (1, 1) I've tried to solve the gradient vector of the function by trying to differentiate the x and y values of the unction. I'm just unsure how to do this when
