Integration

Just a little info on how I'm getting on with the Advanced Higher Maths course: after a lot of both hard work and fun, I have finished Pascal's triangle, Partial fractions, and Differential calculus and its applications. I am currently working on Integration, and have managed to make some progress, although I did find some of the substitution questions impossible! I have just started to do this substitution with limits, and I'm finding it pretty easy, although there was one question which didn't make any sense! I also have more difficult substitution in the next exercise, so we will see how I manage tomorrow.
