Can someone give an explanation of how such a proof would go, given a function example: $y = f(x)$

Use spherical coordinates to evaluate the triple integral: $$\iiint_{E}{(x^2+y^2+z^2)dV}$$ Where E is the ball: $E=\left\{(x,y,z)\in \mathbb{R}^3 \mid x^2...

From what point should I look when determining what trig ratio to use? If they can use hypotenuse over opposite, they can also use opposite over hypotenus...

The following question is on my homework assignment that I cannot figure out: Let U and V be independent random variables, each having a normal distributi...

Sorry for asking such question. I have a very basic understanding of $\arcsin, \arccos, \arctan$ functions. I do know how their graph looks like and not m...

I have this linear system: $$ \left\{ \begin{array}{r} x+2y=4 \\ y-z=0 \\ x+2z=4 \end{array} \right. $$ This Linear system can be converted to echelon for...

Consider a linear differential operator $$L=\frac{d^2}{dx^2}.$$ How would one determine that the normalised eigenfunctions of $L$ are $$\phi_n(x)=\sqrt{2}...

How to find the arc length parametrization of the Archimedean spiral? I know the curve is defined in the complex nubmer like this: $c(t)=e^{it} - ite^{it}...

If this is a grid What do you call it when it's a circle like this? Excuse the poor artwork.

I would like to find out the particular integral (P.I.) of the differential equation : $$(D^2-5D+6)y=e^{2x}$$ Result: P.I. of the D.E., $F(D)y=X$ is (i) $...
