I have a suggestion: a physics calculator - I made one when I was at your level of programming, and it helped immensely in my physics class... look up the NYS regents reference tables if you don't have any already... I only suggest those because I don't know of any better physics references (although I know plenty of others on this site do)
I dont know anything about phisics.
Is it possible to make anything that can help me with problems like this=
y+3x=3 solve for y y=3/-3<<then simplify to -1<< +-3x
(its a graphing thing)
the fomula is y=mx+b I just need it to get y by itself
