This is a quick trick for finding the square of two-digit numbers.
Read MoreMost people thing long division is boring and tedious, but when you understand the math that's going on behind the scenes, it's actually pretty cool!
Read MoreVertical asymptotes are important boundary lines for a function, because, if you can find them, they're a line that the graph cannot cross, which can really help you sketch a more accurate picture of the curve.
Read MoreCritical points are one of the best things we can do with derivatives, because critical points are the foundation of the optimization process.
Read MoreLinear approximation, or linearization, is a method we can use to approximate the value of a function at a particular point.
Read MoreWe already know that the slope of a function at a particular point is given by the derivative of that function, evaluated at that point.
Read MoreMost often in calculus, you deal with explicitly defined functions, which are functions that are solved for y in terms of x.
Read MoreL'Hospital's rule is so named because i was discovered (maybe) by the mathematician L'Hospital in the 1600's.
Read MoreWhen we talk about differentiability, it’s important to know that a function can be differentiable in general, differentiable over a particular interval, or differentiable at a specific point.
Read MoreWhere Green's theorem is a two-dimensional theorem that relates a line integral to the region it surrounds, Stokes theorem is a three-dimensional version relating a line integral to the surface it surrounds.
Read MoreTangent lines are absolutely critical to calculus; you can’t get through Calc 1 without them!
Read MoreIn this video we’re talking about everything you need to know about matrix multiplication.
Read MoreDifferential equations are usually classified into two general categories: partial differential equations, which are also called partial derivatives, and ordinary differential equations.
Read MoreThe only numbers you can plug into a logarithm are positive numbers not equal to 1.
Read MoreImaginary numbers are any numbers that include the imaginary number i.
Read MoreYou’ve heard about similar triangles, but do you know what technically makes two triangles similar?
Read MoreEver wondered what a partial sum is? The simple answer is that a partial sum is actually just the sum of part of a sequence.
Read MoreOur math teachers always tell us to "rationalize the denominator", but most of the time they don't tell us why.
Read MoreWe know that Riemann sums estimate area, and we know that integrals find exact area.
Read MoreIn this video we talk about why the integration by parts formula actually works.
