Thank you so much sir, actually i got the same answer as you. But according to the answer key, there is a negative sign infront, i.e. -1/2 e^-2/t + C. Any idea why?
I did check the answer by differentiate it. Either the answer key is wrong or both of us are wrong in somewhere. May be you can double check with your friend or the person who design the question.
Thank you so much Sir, really appreciate it. Cheers
