WebJan 8, 2015 · 1 Answer. Sorted by: 3. Matrix calculus is used in such cases. Your equation looks like it's from OLS (least squares) theory. In those you differentiate by vector x some quadratic forms like ∂ ( x ′ A ′ A x) ∂ x. Look up relevant formulae in my link above. If you really are up to differentiating by matrices not vectors, you'll end up ... WebThe derivative of a function represents its a rate of change (or the slope at a point on the graph). What is the derivative of zero? The derivative of a constant is equal to zero, hence the derivative of zero is zero. What does the third derivative tell you? The third derivative is the rate at which the second derivative is changing.

WebMay 26, 2015 · We normally calculate the derivative of normal density w.r.t its parameters, mean and variance. But can we calculate the derivative of normal distribution wrt the … Webe^x times 1. f' (x)= e^ x : this proves that the derivative (general slope formula) of f (x)= e^x is e^x, which is the function itself. In other words, for every point on the graph of f (x)=e^x, the slope of the tangent is equal to the y-value of tangent point. So if y= 2, slope will be 2. if y= 2.12345, slope will be 2.12345.
