What is the residue of the function f(z) = (z^2 + 1) / (z^3 - 2z) at the point z = i?

What is the fxx, fyy, and fxy of f=(2x^4)+(y^2)-(x^2)-(2y)?

q(x) = x^2 -12x + 34 find the average change of q on the interval [3,5] & [5,7] how could this be foreshadowed

Find p′(t), p′′(t), and p′′′(t) for the function p(t) = t^(100)+ 4e^(t)+ 16. (You can use rules or shortcuts, but you must write which rules you’re using.) Give clear steps and explanations.
