Try using the Law of Cosines to set up your equations for related rates. As StatusX said, set up your equations w.r.t time.

If you use the formula: \frac {\partial z}{\partial x} = -\frac {\frac {\partial F}{\partial x}}{\frac {\partial F}{\partial z}} then you will get an answer with only x, y and z in it. The function F has a constant value of zero when you create it by moving everything to one side of the...

Yeah, that trick works as well to find dz/dx. It will give you something in terms of x and y...after all when taking partials with respect to some variable you will get all of those variables in the result.

Check the math on the x side of the equation when you integrate.

q_1 and q_2 represents the net charge of the atoms. For example, if you have Fe^2^+ and Cl^-, then q_1 and q_2 would be 2 and 1, respectively. The second number would be positive because it accepts a negative charge by default, making the answer a positive number.

The numbers you did get indicate that it is that depth at either side of the ellipse.

You could put the center of the ellipse on the origin here. It should not matter in terms of the geometry of the ellipse itself.

You can use the endpoints of the interval as well as x = 4. You are allowed to use the endpoints because they are included in the interval.

If each car is traveling at a constant speed as you say, then neither car is accelerating, which means that once car A passes car B, car B will not overtake car A again.

A lot of the dimensions are curled up into small shapes only visible at the Planck length, which accounts for why we don't experience them in everyday experiences.

This involves a portion of the Fundamental Theorem of Calculus which says: The function: F(x) = \int_{0}^{x} f(t) dt is an indefinite integral or antiderivative of f. That is: F'(x) = f(x) Explicit form is simply in terms of a function F.

The only thing to consider for this problem is the acceleration due to gravity and the height of the ball from the bottom of the elevator. The speed of the elevator is irrelevant because its acceleration is zero. Use the same equation, but use the following numbers instead: a =...

a) The formula \vec{c} \cdot \vec{d} = |\vec{c}| |\vec{d}| \cos \theta takes the cosine of the angle between the two vectors and multiplies the result by the magnitudes of the two vectors. The angle between the two vectors is (-226° + 360°) - 62° = 134° - 62° = 72° = \frac{2\pi}{5} The...

My guess would be that it stands for time. The wave function would spit out the probable position of the electron in that orbital.

For a parabola, only one squared term is present, either on the x or y. The fact that there is only one squared term in that general form is what generates the parabola, which could be considered a function if the parabola is not turned on its side. Think of the other three conic sections...
