SIN
−1
Calculates the arc sine of a 32-bit floating-point number and places
the result in the specified result words. (The arc sine function is the
inverse of the sine function; it returns the angle that produces a
given sine value between −1 and 1.)

COS
−1
Calculates the arc cosine of a 32-bit floating-point number and places
the result in the specified result words. (The arc cosine function is the
inverse of the cosine function; it returns the angle that produces a
given cosine value between −1 and 1.)

Calculates the arc tangent of a 32-bit floating-point number and
places the result in the specified result words. (The arc tangent
function is the inverse of the tangent function; it returns the angle
that produces a given tangent value.)
