Alevel integration is really bothering me, and i would appreciate if anyone could help me with this question.
given that x=1, and t=0, solve the differential equation;
hence: express this function given a subject to
thank you in advance.

It's the easiest dif. eq. there is. All you have to do is separate the variables and you get dt=100/(x^2(10x)dx. Integration gives you t=(x*log(x)x*log(x10)10)/x+C. Since t=0 when x=1, you have 0=1*01*log(9)10/1=9.954242509 + 1.36437635 i, therefore C approx 9.951.36i.
Of course, I have been known to be wrong before, and it is odd that your problem involves complex numbers. Eh, I've prolly made a mistake somewhere, but I can't figure out where.
I worked this out without any imaginary numbers, but I used that fancy little trick that matt A used to get there. The problem with that is that it's cheating or something.
HAve you made a mistake here?Originally Posted by Heinsbergrelatz
Shgouldnt it be
not
ie dt/dx not dx/dt?
