Which did you find most difficult? I don't have time to do every past paper (I've done most of the Solomons though) but I'll do any which you could recommend :smile:

What are these negative solutions??

Last two papers I did 90%+ hopefully it stays like this

I think he means questions like this:

Solve, for –90° < x < 90°, to 1dp:
tan (3x + 20°) = 3/2

If you're talking about the area between two curves, then yes it is very easy.

One curve will be below the other. You integrate the lower curve and take that away from the integral of the higher curve. Simple as that

thanks, I have never had that explained to me! hope this works :smile:

appreciate it!
