As of a few days ago I'm now the proud owner of Labview for lego mindstorms. I was excited to begin programming and decided to start with a algorithm I've come up with for a lego cannon. It hinges on the the computation of the arcsine of an input, yet the program does not have an arcsine function. My question is whether there is a way to express arcsine with the trigonometric functions included in the kit (which include sin, cos, tan and arctan)? I'm a VERY novice labview programmer and am only acquainted with mathematics up to an introductory calculus level so simplicity and patience would be very much appreciated.
