Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. 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?!”

Glad you like my teaching style! I take that as a huge compliment since patrickJMT is so good at what he does.

Your a life saver! I have one of those teachers that 70yrs old and thinks everything is self explanatory in calculus. Your videos clear up everything so much and i would never have passed calc1 or 2 if it wasn't for you! thanks again, its test time now haha

@Acrylics25 Yep! Sometimes the functions intersect each other at more than two points. If that's the case, then you need to figure out which function is above the other one between each of the intersection points. :)

All of your videos are amazing. You take complicated concepts and make them look so easy. I couldn't have gotten through Calc I last semester and now Calc II this semester without your help. Thank you so much! I recommend your channel to everybody I talk to that needs help in calculus :)

I'm so glad you like them! Thanks for the comment. :)

You literally saved my life in my Calc 2 test. The equation that you had there for the area wasn't even in the book!!! Thanks so

Finding your videos so helpful, you truly are an expert.

Hi,
Wondering if we could have just integrated from 0 to Pi/3 and multiply 2 in the front cuz it looks like we could apply symmetry..just wondering as I'd rather work with possible theta, not negative

@Nicola72av You're welcome! :) o[ ]o ! :)

Your videos are extremely helpful! Your Awesome! :D

Under the formula for the area what is the significance of the equation that we use to substitute with

[DelGeeZee]

My final answer ends up being (5*root3)/2 - pi/3 . No need to simplify because its still gibberish. Then I take the time that I saved simplifying and put it toward the next question. Walla!

I wish girls looked like you in my engineering class. :)
