Let's say I have a [nXn]-matrix (i.e ), which is a function of three time dependent variables (i.e. ) and I need to find the partial derivative , whereqis the vector . Moreover, I need to find the time derivative . I know this question might be a very simple one but I ...
Could you let me know how to sovle the partial derivative of magnetic flux density, pd(mef.Bx,x), by change any option in the model? Thanks,
2. Write function next to the fraction in partial derivative Now let’s see what the optional arguments do: First we have the asterisk *, which determines where the function is typeset. If the asterisk is not present, the function is typeset in the numerator of the fraction, as in the...
where the partial derivative with respect to each can be written as To summarize: in order to use gradient descent to learn the model coefficients, we simply update the weightswby taking a step into the opposite direction of the gradient for each pass over the training set – that’s basical...

Why is the derivative negative? As dg increases, the denominator gets larger, the total value gets smaller, so we're actually shrinking (1/3 to 1/4 is a shrink of 1/12). Why do we have -1/g^2 * dg and not just -1/g^2? (This confused me at first). Remember, -1/g^...
4. How do I use the second derivative test to determine the nature of a critical point? The second derivative test involves finding the second-order partial derivatives of the multivariable function at the critical point. If the second derivative is positive, the critical point is a local...
The fundamental theorem of partial derivatives states that if a function has continuous partial derivatives in a region, then the order of differentiation does not matter and the mixed partial derivatives are equal. How do I apply the fundamental theorem to partial derivatives?
The integrand is a rational function, that can be integrated via a partial fraction decomposition; however, be warned that such a solution might need its own nonzero constant of integration to ensure that the initial condition is fulfilled. 2.3 Special cases There are some noteworthy cases for ...
