i'm having trouble with this. i first need to solve x'=sinx. the answer is given as t=ln|(csc(x0)+cot(x0))/(csc(x)+cot(x))|] i'm not sure where those x0's came in from. here's what i did: Int(1/sinx)dx=Int(1)dt Int(csc(x))dx=Int(1)dt Int((-1)[(-1)csc(x)(cot(x)+csc(x))]/(cot(x)+csc(x)))dx=Int(1)dt (this is the same as the line above but then lets you change Int(f'(x)/f(x)) to ln(f(x))) -ln(cot(x)+csc(x))=t so as you can see this answer isn't the same as the answer that was provided. what am i doing wrong and where do those x0's come in from? any help is appreciated.
