..Or I think this is considered that... Here's the problem as written then I'll get to it: Find the lenght of the curve y^2=x^3 from the orign to the point where the tangent makes an angle of 45 degrees with the x-axis. Okay, by me posting this, I don't want anyone (nor am I looking for someone) to give me the answer. ...that being said, I feel completely comfortable saying I don't have the FIRST clue of how to start this :) So if someone could just help give me a kick-start on this, I'll do my best to take it from there! Thanks guys.
