In math, we’re very used to working with equations in the form y equals something in terms of x. Sometimes, it seems that’s all we do in high school math! We’ve learned that x is called...

Recall that in order for a function to have an inverse function, it must be one-to-one or pass the Horizontal Line Test (HLT). None of the six trigonometric functions pass the Horizontal Line Test...

When you reach a certain point in your math career, perhaps around 8th or 9th grade, you likely learned about the Vertical Line Test, which is a test that determines if a relation is a function....

“Correlation does not imply causation.” This statement has been uttered so many times in stats classes, the statement has almost become a cliche! What does it really mean though? In this...

A hyperbola, in analytic geometry, is a conic section that is formed when a plane intersects a double right circular cone at an angle so that both halves of the cone are intersected. The intersection...

What is a sinusoidal function? If you’ve taken precalculus or even geometry, you’re likely familiar with sine and cosine functions. Does SOH CAH TOA ring any bells? Once trig functions have...
