Re: Integration

dy/dx dy doesn't really make sense. Think of the two 'dx' canceling each other when you do the integration.

You need the A since the two constants are different; one is additive and the other is multiplicative. The A is actually A=exp(alpha), where alpha is an additive constant of integration which is lodged inside the exponent.
