If a function is known to have
fx(30,24) = -.4
fy(30,24) = 1.2
f(30,24) = 50
Estimate this value of F.
f(30.2,23.9)
Thank you in advance! I am stuck on this part. Both s and y changed and have no idea what to do.
the idea of approximating a two variable function around a given point is to use the tangent plane (at the given point) to the surface that the function represents as
the approximation, i.e. so if we put and use the given info, we'll
