# Differential Equations

## Learn everything from Differential Equations, then test your knowledge on 55+ quiz questions

How this Differential Equations course is set up to make complicated math easy:

This approximately 40-lesson course includes video and text explanations of everything from Differential Equations, and it includes more than 55 quiz questions (with solutions!) to help you test your understanding along the way. Differential Equations is organized into the following sections:

• First-order differential equations
• Second-order differential equations
• Laplace transforms

And here’s what you get inside of every lesson:

Videos: Watch over my shoulder as I solve problems for every single math issue you’ll encounter in class. We start from the beginning... I explain the problem setup and why I set it up that way, the steps I take and why I take them, how to work through the yucky, fuzzy middle parts, and how to simplify the answer when you get it.

Notes: The notes section of each lesson is where you find the most important things to remember. It’s like Cliff Notes for books, but for math. Everything you need to know to pass your class and nothing you don’t.

Quizzes: When you think you’ve got a good grasp on a topic within a course, you can test your knowledge by taking one of our quizzes. If you pass, wonderful. If not, you can review the videos and notes again or ask me for help in the Q&A section.

Here's what some of my Differential Equations students have told me:

“The course is very easy to follow due to her great ability to explain even complex methods in an interesting way.” - Benedict V.

“She is an absolute star teacher.” - Vassilios K.

“I wanted to follow up on my review(s) of the calculus master series now that I have completed calc 1, 2 and 3. I can say without a doubt that without Ms. King's clean, exhaustive explanations of each topic, I would have been truly lost. However, because of the combination of written, detailed instructions with examples, videos performing even more examples, and then quizzes to see if I comprehended what I just learned, I self-taught myself through 3 online calculus courses (one was in the summer, with 2 bored kids) and got a 92, 95, and 96. I was the highest scoring student in calculus 2 by half a letter grade, and the teacher still talks to other teachers about how much she enjoyed grading my work because it was so clean. This is because I adopted the methods Ms. King used! So, if you are on the fence because she also has many videos on youtube, just let me point out that the written guides and examples are so great for test review that you will never feel lost in class. Also let me point out that my classes only covered roughly half of Ms. King's material. There were so many bonus problems and more in-depth topics in these courses that my class never covered (not to mention a fairly in depth beginning to differential equations in calc 3, which I am now using in differential equations) that I definitely feel like I got my money's worth!” - Jennifer L.

Math class was always so frustrating.

I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half.

I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep others out of that aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
