So, arcsin (y) - arcsin (x) = C would now be my final general solution, right?

Thank you. I get it. however, I don't see it. Sorry. Can you explain it further? I do not see anything wrong with it, though.

Homework Statement [/B] (dy/dx)^2 = (1-y^2) / (1-x^2)Homework Equations Separating the variables I arrive with: dy/sqrt(1-y^2) = dx/sqrt(1-x^2) By integration on both sides by trigonometric substitution and putting it in a general solution: Arcsin y - Arcsin x = C The Attempt at a Solution If...

Okay. Thank you. :)

okay. So there ain't any reversing the process in a relation?

wow. Did not see that either. thank you

thank you guys for all the responses. I really appreciate it. It is somehow becoming clearer. But another question: In calculus, why does it uses just function and not relation?

thank you. This is a great help. but what kind of reversibility?

yes and this is where the comes in.The word "function" relates two things in a special way which applies in both languages. Just that in mathematics, it demands an exact value while in your economics example it was a mere statement of the relationship between the 2 things, right?

I understand. Is the one we are calling the "function" is the formula itself?

thanks for that. then how about the function which is like a "machine thing"? In what sense exactly?:confused:

why does a function have to be called function? Can't it be just be called a relation, for instance, of 2 variables? the word function is confusing me. Of course, I have searched and read its definition but i just can not get it. I could just set it in my head but I don't understand it well enough.

decided to be a member with hopes i can learn from you, geniuses, some of your greatness you are willing to share to help someone like me who is making my way to become a chemical engineer someday, hopefully. likewise, I will also share what i have as much as i can. so let us help each other guys.
