Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:

Let h(x, y) be a differentiable function and let (xo, yo) be a point in the domain of h. Also, let u be a unit vector. Then D- h(xo, yo) = -Du h(xo, yo). Hint: Your job is to show that two directional derivatives are related. First notice the two negative signs. One of them is the negative of a VECTOR. Start by computing the directional derivative on the LHS. Remember that for the dot product, a (-b) = (-a) b=-(ab).
Suppose ƒ is differentiable at (9, 9), ∇ƒ(9, 9) = ⟨3, 1⟩, and w = (1, -1). Compute the directional derivative of ƒ at ⟨9, 9⟩ in the direction of the vector w.
Let r(t)=(10 cos(t), 1, 10 sin(t)). Find the unit tangent vector u drawn to point P-(6,1,8). Sketch curve and tangent.
