My Casio fx-9750 GIl gets an "Ma error" if say I plug in sin^-1 8/15. Is there any solution? Can I do it without a calculator? Actually I plugged in .53 instead of 8/15, problem solved.

Thank you guys very much, right now my goal is calculus and differential equations. They can both help me in my economic and physics observations. I feel like I'm climbing a mountain. Awesome, I always wondered how parabolas were measured. I find these very useful ^___^

I know the Layman of QED and GM. I don't know the math that acts as a proof for it, even though I know it had singularities somewhere and QM is the best thing we have.

Hello everyone, I am looking forward to understanding physics in depth. Unfortunately, I've been screwed by my school system and I'll be taking Pre-Cal in community college(from there I hope to get in a good 4-year). I am in the process of teaching myself Algebra 2. I am almost done. I know basic physics, I know General and Special relativity, and read QED by Feynman. Thats about it. I want to study deep physics and I am really intimidated by the math you guys use because I don't understand it. So I'm processing everything in the Layman, but I want to study deep and pure equations. I was focused heavily on social sciences until I found a "handy physics answers book", which gradually swerved my interests. I also feel extremely embarrassed by the fact that I am a year behind (almost)everyone in Math. Hopefully I can learn some great things from this forum!

Thats not hard to figure out. Just some math and experiments.
