Great app, minor problem. But still love it


Well I just started using this app since yesterday and I woke up in the middle of the night and I just started studying more of these videos, however I came across video (#7) where it seems you have stated in the end that Sin=pie/1 and Cos=pie/0 then you have Tan=1/0; I thought that Tan=X/Y therefore stating that Sin should equal pie/0 and Cos should equal pie/1. I only say this because I don't think people should get confused with these problems henceforth; possibly put a side note into that video to let people know. But maybe I'm wrong, I just started yesterday after all.

Very helpful but has room to improve.


The app has been really helpful as my precalc textbook that I had to buy for class is terrible (thanks, Pearson). However, it's really really annoying how the presenter clearly is talking based off bullet points or on the fly because he regularly interrupts himself and makes mistakes. When you're recording a video that can be redone easily it makes little sense not to edit out the errors. Again, very grateful for the free app but just some advice going forward.

Are the videos supposed to be silent? Also, please remove Ben's comment about the Teachers' Union. Poor teaching has everything to do with a person's ability to connect with other people; political or social affiliation are irrelevant. Though I'm sure K.A. loves the praise, it loses value when it is earned at others' expense. You're clearly conservative, go back to your faith to find forgiveness and release the hate passively before 'vomiting information just to hear yourself speak.'
