Err...Help?

asin(sin(x) = x

tan(atany) = y

cos(acosz) = z      Does that help?

=xyz

asin(sinX) tan(atanY) cos(acosZ) =

(X) * (Y) * (Z)

[ This may be a little hard to see but, for example...let X  =pi/6, Y = pi/4  and Z  =pi/3....so

asin (sin (pi/6) ) * atan (tan (pi/4) ) * acos (cos (pi/3) )  =

asin (1/2) * atan (1)  * acos (1/2)  =

pi/6 * pi/4 * pi/3  =

X * Y * Z   ]
