While my math struggles continue. I find my self asking if this is the right major I want to chose (astrophysics) i'm in precalculus college level lol.. We are doing domains of comp functions.. and I find it all pointless.. Im very good at algebra and trig...(adsbygoogle = window.adsbygoogle || []).push({});

Is this fog (x) stuff really used much when it comes to physics?

I love astronomy witch got me into physics.. I want to research and learn about the universe and space.. Not domains of functions.. Are domains even needed realistically when it comes to astrophysics? Maybe some mathematicians can help me out. When I look at formulas and equations like gravity, gen relativity. They seem so simple e=mc^2 etc.. And all the formulas look like sqrt over a fraction etc.. Simple stuff, so why do I need to learn domains and functions. ?
