Parents of AP Calculus students — does your child know what to do when an equation has both x and y in it and y is not isolated?
This is where many students discover that simply memorizing derivative rules is not enough.
Implicit differentiation requires students to recognize what is happening, differentiate correctly with respect to x, and keep track of dy/dx along the way.
In this short video, I demonstrate how to handle this important AP Calculus skill step by step.
If your child is struggling with AP Calculus or you want them better prepared for what is ahead, send me a message.

Parents of AP Calculus students — is your child getting the right answers on homework, but struggling when the test asks the same concept in a slightly different way?
Finding the equation of a tangent line is a fundamental AP Calculus skill, but it requires more than memorizing a formula.
Your child needs to understand how the derivative, slope, and equation of a line all connect.
In this short video, I show how to approach a tangent-line problem clearly and efficiently.

Parents of AP Calculus students — would your child know how to handle a limit involving trigonometric functions?
Problems like this test whether students can recognize a familiar limit hidden inside an expression that looks different.
That ability to recognize patterns is critical in AP Calculus. It is not enough to memorize a rule—students need to know when and how to use it.
In this short video, I show how to approach this type of trigonometric limit clearly and efficiently.
If you’re concerned that your child knows the formulas but struggles to recognize when to use them, send me a message.

Can you find a derivative without using any of the usual derivative rules?

In this short video, I’ll show you how to find a derivative directly from the definition—and why this fundamental idea matters in calculus.

If your child is taking AP Calculus and could use help truly understanding the concepts instead of just memorizing formulas, send me a message to learn more about how I can help.

Piecewise functions are a common place where students get tripped up on continuity.

In this short video, I’ll show you exactly what you need to check to determine whether a piecewise function is continuous at a particular point.

If your child is taking AP Calculus and could use help understanding concepts like limits and continuity, send me a message to learn more about how I can help.

Do square roots make derivatives seem harder than they need to be?

In this short video, I’ll show you a simple way to handle derivatives involving square roots by rewriting the function first.

If your child is taking AP Calculus and could use help understanding the ideas behind the formulas, send me a message to learn more about how I can help.

Limits involving trigonometric functions can look more complicated than they really are.

In this short video, I’ll show you how to recognize the key idea and solve this type of limit quickly.

If your child is taking AP Calculus and could use help building a stronger understanding of the material, send me a message to learn more about how I can help.

Every August I see the same thing.

Bright students begin AP Calculus with confidence...

Then a few weeks later they start falling behind.

Not because calculus is too hard.

Because they're trying to relearn Algebra II while keeping up with new calculus concepts.

This short example shows exactly what I mean.

A little algebra review now can save a lot of frustration later.
