Hey, I've gotta brush up on my integration / differentiation before the september term and have come across a question that's giving me trouble (well.. a few tbh but I might go back to them later..)
Cut-down workings:
solve, given x=10, t=0
rearrange and differentiate with respect to x
And this simplifies /rearranges to:
Problem
According to the textbook, the answer should be:
The closest I've gotten so far is as follows:
t is given in the question as 0, therefore:
if , then
x is given as 10, therefore:
However, I'm probably going at it slightly wrong since I can't get A=10 to become c=10 ...
Any help?
Thanks,
