apoligies made a mistake it should read dy/dt so it is A below

Thanks Mr Fantastic, just to check, if i rearrange for y I get the following: If I then try and calculate the partucular solution that satisfies initial condition: y(1)=5 I get C =

The square root goes over the 1 as well. 2. It's probably easier to sub t = 1, y = 5 into : etc.
