- Use the gradient to find the tangent to a level curve of a given function. The right-hand side of the Directional Derivative of a Function of Two Variables is equal to f x(x,y)cosθ +f y(x,y)sinθ f x (x, y) cos θ + f y (x, y) sin θ, which can be written as the dot product of two vectors.

The tangent line to a curve at a given point is the line which intersects the curve at the point and has the same instantaneous slope as the curve at the point. Finding the tangent line to a point on a curved graph is challenging and requires the use of calculus; specifically, we will use the derivative to find the slope of the curve.
Given an $n\geq2$, a function $f: \>{\Bbb R}^n\to{\Bbb R}$, and a point $p$ define $q:=f(p)$. The set $$S:=f^{-1}(q)=\{x \>|\>f(x)=q\}$$ is called the level line (or level surface) of $f$ through $p$.

find the points (a, b) (a, b) of the plane that satisfy the tangent of the level curve M = f(a, b) M = f (a, b) in the point (a, b) (a, b) passes through (0, 1) (0, 1). I tried solving this simply by using the equation of the tangent to a level curve: fx(a, b)(x − a) +fy(a, b)(y − b) = 0 f x (a, b) (x − a) + f y (a, b) (y − b) = 0 ...
