WebMay 26, 2024 · This means that B ( A ⋅ C) is just the vector B scaled by a real number. This operation is well defined. While the proof is slightly involved, some sanity checks can be instructive. For example, we expect that ( A × ( B × C)) ⋅ A = 0 since cross product of a vector is perpendicular to the vector itself.

WebThis is a chain rule, within a chain rule problem. The rule remains the same, you just have to do it twice: differentiate the outermost function, keep the inside the same, then multiply by the derivative of the inside. = sec^2 [ ln (ax + b) ] * d/dx [ ln (ax + b] = sec^2 [ ln (ax + b) ] * (ax + b)^-1 * d/dx (ax + b) WebTo prove the quotient rule using the product rule and chain rule, we can express the function f (x) = u (x)/v (x) as f (x) = u (x)•1/v (x) and further apply product rule formula to find f' (x) = …
