Calculates the tangent of a 32-bit floating-point number (in radians) and
places the result in the specified result words.

ASIN(463)
S
R
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.)

ACOS(464)
S
R
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.)
