The phrase "absolute sine" is correct and usable in written English.
It can be used in mathematical or scientific contexts, particularly when discussing trigonometric functions or properties.
Example: "To find the absolute sine of the angle, we must first convert it to radians."
Alternatives: "exact sine" or "true sine".
