Simple interest is different than compounded, or compounding, interest. With compounding interest, you earn interest on your interest, so that your money grows exponentially…

Read MoreAny nonzero real number raised to the power of zero is one, this means anything that looks like a^ will always equal 1 if "a" is not equal to zero.

Read MoreIn this video we’re talking about jump discontinuities, or discontinuities of the first kind.

Read MoreCommutative comes from the word “commute” as in “the morning commute.” Since commute means to move you can remember that, when using the commutative property, the numbers will move around.

Read MoreWhen you have multiple functions, you can use some simple rules to find their sum, difference, product, or quotient.

Read MoreKeep in mind that present value is the opposite of future value. Future value is how much we need to have at some point in the future; present value is how much we need to have right now.

Read MoreWhenever you're dealing with a multivariable function, the graph of that function will be a three-dimensional figure in space.

Read MoreWhen you hear your professor talking about limits, he or she is usually talking about the general limit.

Read MoreRemember that composite functions are “functions of functions”, which means that we have one function plugged into another function. As an example, sin(x^2) is a composite function because we’ve plugged the function x^2 into the function sin(x). Think of any function that as an “outer part” and an “inner part” as composite functions.

Read MoreRemember that the phrase “rationalize the denominator” just means “get the square root(s) out of the denominator”.

Read MoreIt can be difficult to visualize what a triple integral represents, which is why in this video we’ll be answering the question, “What am I finding when I evaluate a triple integral?”

Read MoreRemember that midpoint rule, trapezoidal rule, and Simpson’s rule are all different ways to come up with an approximation for area under the curve.

Read MoreTrig identities are pretty tough for most people, because 1) there are so many of them, and 2) they’re hard to remember, and 3) it’s tough to recognize when you’re supposed to use them!

Read MoreScientific notation is all about proper form. There’s only format that qualifies as proper scientific notation, and that’s the product of a decimal term and a power of 10. Moreover, the number to the left of the decimal point must be between 1 and 9.

Read MoreEuler’s method is a numerical method that you can use to approximate the solution to an initial value problem with a differential equation that can’t be solved using a more traditional method, like the methods we use to solve separable, exact, or linear differential equations.

Read MoreThe most important thing to remember about graphing lines is that you always need some combination of the slope of the line, and/or points on the line in order to graph it.

Read MorePartial derivatives are just like regular derivatives, but for multivariable functions.

Read MorePythagorean theorem is a tool you’ll use all the time when you’re dealing with triangles, and you will always be dealing with triangles, no matter what math class you’re taking.

Read MoreTrigonometric substitution (more affectionately known as trig substitution, or trig sub), is another integration method you can use to simplify integrals.
