Drawing out the tables to calculate variance using the sum of xi^2 - E(X)^2 is a real pain. I don't know how to find out whether WJEC allows use of the stats functions too.

    Ethan Shaw the Casio is superior in doing DMS calculations, REC-to-Polar calculations, and using the CALC function, because the Casio is far more intuitive in those operations, but that’s all... where the TI36X Pro shines is its power-off memory protection. ALL of your calculation history, in all modes, is saved if you power off and then turn it back on.

Also, what's going on 15:55? integral of e^x sinx dx = e^x/2 (sinx-cosx) thus integral of e^x sinx dx, x = 2 to 5 = e^5/2 (sin5-cos5) - e^2/2 (sin2-cos2) ~= -97.105.

And if you still want the intermediary steps, the magnitude of a vector is often referred to as its "absolute value". So | VctA | = Abs(VctA) which you'll find under SHIFT (
