1. Hello, I thought I make a thread on this because I keep getting stuck on little things while Im revising and Im sure you lot know the answers.

How do you integrate: [x[(x^2)-3]^0.5]^2

Thanks
2. (x(x^2-3)^0.5)^2 = x^2(x^2 - 3) = x^4 - 3x^2....this is now standard integration

hope this helps
3. [x[(x^2)-3]^0.5]^2
[x[(x^2)-3]^1
[x[(x^2)-3]
x^3-3x
integrate have fun
4. (Original post by driving_seat)
[x[(x^2)-3]^1
have u not forgot to square the first x in this line....
5. (Original post by driving_seat)
[x[(x^2)-3]^0.5]^2
[x[(x^2)-3]^1
[x[(x^2)-3]
x^3-3x
integrate have fun
wrong!
6. thanks alot people
7. Differentiate: [x[(x^2)-3]^0.5]
8. (x^2)(x^2-3)^-1/2
