If you do 4U, remember most of a casios have a polar co-ord function (its called Pol, and you enter as Pol(x,y) and it will give you modulus and argument). It saves a lot of time when converting to mod arg and back

Press Shift then find the a button which says Pol in yellow (for natural calculators) and just press the top right button Pol( for older SVPAM calculators.

On the screen you'll get Pol( and just enter your x and y values (with a comma in between) from x+iy to get your modulus and argument i.e. Pol(x,y)

Similarly you can do the reverse with the Rec( button. (that is, you place your |z| followed by a comma, followed by your arg(z))
