So if we simplify that we are going to have uh this is going to cancel down to six so we're going to have 6 ln 8 - 9 + 9 / Part two then says calculate the area of triangle OAB If we expand the brackets we are going to have um 2 * 2 So Okay part two was is a bit of a weird question we've not been asked a question like this before on uh ... would get 2 X cubed takeaway 6 x squared - X cubed take away 6 x squared + ... I get a question like this is to differentiate what they've given us so that we have an expression
So that the negatives cancel that's going to be the same as 12 over 3 so K is equal to So natural log Y is going to equal to natural log 2 plus 1 so 2 natural log 3 minus 3 over 2 plus 1 3 over 3 so that's 1 minus Because that's going to allow these two terms to disappear and we're going to get see this time so when we've got negative
