i was taking my final today and came across an initial value problem. Seemed pretty simple, seperate the variables, integrate, then use the initial value to find the value for the constantt C. The weird thing was that the constant C would be multipled by 0 when i plug in the given initial values. I just stopped and was like what the hell is this. I thought maybe it was a mistake and asked the intructor, but he said it wasn't. After some double checking, I was pretty sure my work up to that point was right. Eventually i gave up and came to the conclusion that maybe C could be anything cause it was multiplied by 0 and just wrote my general solution without the constant C. But its still annoying the hell out of me, cause I've never seen this situation when the constant C is multipled by 0. I talked to some people after the final and it seemed they ran into the same situation too. Can someone please explain the reasoning behind this this question? Sorry i don't remember the exact equation given, I'll try to ask my other classmate if they remember.
