    We work with differential equations a lot in FP2, so I was wondering if there was a "checking method" to check whether the differential equations are correct?

    Yes. Differentiate (possibly twice depending on question), then substitute back in and verify.

    Nope. Find your own example, do what I said, if you have trouble post showing both the question and your working.

    Okay, I'll post it the next time I do a differential equation.

    What about a checking method for Maclaurin and Taylor series?

    Sub a number in. Be careful though that the number you choose is in the correct interval. Eg if you found the series for Tan(x+pi/4), you would need to sub in a number close to pi/4
