Question about Office Equipment & Supplies
It seems that you are trying to calculate the inverse sine (arcsine) of 90. However the domain of definition of the arcsine function is the closed interval [-1, 1]. Any value outside of this interval will result in an error.

because cotangent, cosecant, and secant are all inverse trig functions, just type in 1 / |shift| trig function and the number if you are finding the angles. It might not be a dedicated button, but its an extra push, and it will give you the same result. *note that I put the shift press only because that is how you get the inverse tan to get an angle from a tan ratio.*

It means that you have put the wrong things together. E.X. String>Equ(x,y) when x dont equal a Yvar. and y dont equal a string number (StrZ, Z=#'s 0-9)

inverse sine (sin^-1) gives you the angle when the opposite side length and the hypotenuse, in relation to that angle, are given. therefore, if you want to do sin^-1(x), 0<x<1 for all real triangles ex. sin^-1(1/2) would equal 30. if you get a decimal, then go to [Mode] and select degrees instead of radians to get angle measures instead of radians... :)
