Please help, if you already know the sine of a number, how can you find the number (and the number has to be between a certain set of numbers)
+37091 Use the INVERSE SIN function which is the same as sin^-1 which is the same as arcsin which is the same as asin (on web2.0 calc)
It is not the sine of a number, but of an angle. Once you know the sine of that angle, then you can easily find the angle(in degrees or radians), using the "inverse sine" or the "arcsine". Similarly, if you konw the angle, you can find its sine by a number of advanced methods, such as Taylor's infinite series, which goes something like this:x - x^3/3! + x^5/5! - x^7/7! + x^9/9!.........and so on. "x" is in radians.
