1 04/11/25 2 ======== 3 4 - see FIG1 on how to do intergration by substitution 5 - note that we use x ^ 2 dx = du / 3 to cancel things out 6 - we write it in terms of du 7 - see FIG2 for the formal defintion of intergration by substitution 8 - if you intergrate the chain rule, you should get this 9 - note when doing a definite intergral, the limits change to g(b) and g(a) 10 - if you convert everything back to x from u, before doing the intergration this isn't needed 11 - see FIG3 for a worked example of a substituion 12 - see FIG4 for some helpful tricks on odd and even functions 13 - not needed to be known, just makes things faster
