Hi, I'd doing question 1 of the attached sheet and just wondered if someone could help me out. I'm a bit unsure of my calculus and need it reviewed, alsoam not entirely sure how to break down my workings (using the supplied equations in the hint) to find C. So any input would be greatly appreciated.
The Attempt at a Solution
See the attached files - ps is there any software that I can use to write equations on this forum, mathtype would be nice, but I can't seem to cut & paste from it to here.
