In Maple, do, ?radian ?convert,radian On your calculator, look in the manual to see if it has both a degree ("deg") and a radian ("rad") mode. If so, try to switch between them and see what happens to the results from the trigonometric function keys. Next, consider what you see Maple return for these examples, sin( evalf(45) ); sin( evalf(45 * 2*Pi/360) ); 45 * 2*Pi/360; There are 2*Pi so-called radians in the 360 degree that form a complete revolution of a circle. This form of expressing angles is used so often by mathematicians that the term radian is often dropped, and one may speak simply of the sine of "2 Pi" or of "one quarter Pi" and so on. The radian term has just become implicit in that phrasing. Lots of scientific and engineering calculators these days can switch between calculating in the two distinct modes. One mode is where the radian term is implicit, and one is where the degree term is implicit. If you ask, "well, isn't the radian a bizarre arbitrary fraction of the whole circular revolution?" then one could answer that the degree is an equally arbitrary and whimsical portion of the whole. The degree is based in astronomy -- that there are close to 360 days in a year, and that 360 has lots of convenient prime factors. The radian actually seems less arbitrary, being based on the angle that sweeps out an arclength along the circumference of exactly one radius of the circle. acer

Could you pass some of the purely numerical scalar parameters (of your 33 total) in just one or two arrays? For example, could you pass all your integer parameters in one array, and all your floating-point parameters in another array? acer
