sin(value) cos(value) tan(value)
You can use the inverse trig functions (arcsine, y ?; arccosine, y
@; and arctangent, y A) with real numbers, expressions, and
lists. The current angle mode setting affects interpretation.
sinL1(value) cosL1(value) tanL1(value)
Note: The trig functions do not operate on complex numbers.
^ (Power), 2 (Square), ‡( (Square Root)
You can use ^ (power, ›), 2 (square, ¡), and ‡( (square root, y C)
with real and complex numbers, expressions, lists, and matrices. You
cannot use ‡( with matrices.

L1 (Inverse)
You can use L1 (inverse, œ) with real and complex numbers,
expressions, lists, and matrices. The multiplicative inverse is equivalent
to the reciprocal, 1àx.
