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?!”
So I started tutoring to keep other people out of the same 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.

Am most grateful for the Integration Chain Rule refresher at min 10:30 .

[@kristakingmath]

I'm so glad I can help along the way! :)

[@wilfordmadyira1898]

hello Krista how many loops should be there

[@kristakingmath]

If you haven't already, I explain the process here: integralcalc . com/how-I-create-my-videos/ and during the video editing process with screenflow, you can replace the cursor with an image. :)

[@bscmsc70]

Thank you for the effort and the time. This is a great video

Dear Krista, I apologize for asking but do you have a video on harmonic analysis? thank you very much.

[@kristakingmath]

Sorry you're having trouble! Send me a contact message here and I'll be able to better help you: integralcalc . com/contact/

I know you use SketchBook for making these videos, but how do you change the cursor on the Mac to look like a piece of chalk? Thanks!

[@prajyotpatil1879]

Hello mam,Thank you . can you make more videos on different examples?

[@kristakingmath]

Yes, soon!

Hi, I have been unable to download the ebook... I have tried both on Chrome and Safari, any thoughts?

[@lemonsnpickles]

u have a beautiful voice :)

[@kristakingmath]

between two polar curves? this is one: youtube . com/watch?v=Dj_yzASuLcE

[@matiasjx5535]

i like it

[@kristakingmath]

:D

[@GodMowsMyLawn]

Why do u set, 3theta=pi/2 ?

[@kristakingmath]

Because 3theta is the argument inside the trig function, and you always want to take the argument and set it equal to pi/2. Doing so will always make it easier to find the values you need later.

[@GodMowsMyLawn]

+Krista King so i could set it equal to pi/4 hypothetically and it would work or would it be wrong?

[@kristakingmath]

No, you always want to set it equal to pi/2, not any other value.

[@GodMowsMyLawn]

+Krista King oh ok thank you very much 😁

[@lifeinvestments3954]

@kristakingmath does it matter which trig ratio we are using, or we always set the angle to pi/2 irregardless

i'm just resting my eyes...
