I don't know what kind of help you're expecting with the (lack of) information you provided.

The sign just means to integrate whatever is 'beside' it.

yea, i bet most people who can help you here no longer have access to a c1 textbook...

but from what i see that your saying, if the question is just a function beginning with an integral sign, the question is just asking you to integrate for x or y or whatever the variable is. if there are limits, you do as before, except then, you substitute the lower value into the integral and subtract this from the the value you get from substituting the upper limit.

You answer the question in ex 8C exactly the same way as youhave been doing for 8A/B. THe integral sign is just another way of saying 'find y when dy/dx is given by following expressions'

I hope this helps, but just to say i am using the old C1 textbook, so the info might not be relevant, but i hope it is

if you're on OCR then you're looking at the wrong section... there is no integration in C1.

Maybe by mentioning what textbook you are referring to would be useful... ¬¬
