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?!”

Thank you for the thorough explanation. Helped a lot. Glad I found you!

Thank you, great explanation and your 'hey everyone' always cheers me up :)

I have literally started watching all of your trig sub videos, so glad there are so many! They are all very helpful. Keep making more videos:)
Thanks, xo Perla

@AXIAM79 Glad you think so, especially since calculus isn't too cheerful of a topic for most people. :)

@HeartOf30STM You're welcome very much. :)

Alright, so you've helped me understand, but I still have no idea how I'm going to remember EVERY trigonometric identity this Friday.... :P

[kristakingmath]

@BoneCrusher737 you do what you can :)

[johariedilangalen]

can you show some examples using completing the squares?

[kristakingmath]

@mpatt79 Hahaha, you're welcome! Too bad you can't skip that hefty tuition bill, huh? Maybe someday all education will be free! :)

At 2:24 you speak of "raising to the base sin^-1" - this is potentially confusing, as some people could think you mean 1/sin (or csc). Specifying arcsin or inverse sine (even if you still write it the same way) might be far less ambiguous.

Otherwise an excellent presentation.

You're looking at your reference sheet to find the derivative of sin?
