Question about Casio FX-115ES Scientific Calculator
I usually can do inverse sine, cosine etc fine. However, today I tried inputting arcsin(20/1) which means inverse sin(20/1) but it says math: ERROR. HELP???
The sine and cosine function have a range between [-1, 1]. The domain of their inverse functions is [-1,1]. So 20/1 which is 20 is out of the domain of definition of the functions. No limitations for tangent and cotangent.

SOURCE: Hi How do i do sin
You may be working in degrees when you need to be in radians, or vice versa.
Press the MODE button until it offers you the choice D R G (Degrees, radians, grads) and select the corresponding number. Then try again.

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.*
