Question

Why does a calculator return an error when trying to find inverse sine of 1.055?

Answer 1

The calculator returns an error as the answer for the inverse sine of 1.055 because the acceptable range for sine is only from 0 to 1.00 in which 1.055 is clearly greater than. This is also the same as for the cosine values. 

Answer 2

Answer:

Calculator shows error because maximum value of inverse of sin function can be one.

Step-by-step explanation:

The range of sin x is $-1$

So, it is of no use to find the value of $sin^{-1}(1.055)$

Because range is the value of the output of the function which is maximum 1 in case of sine and cosine function.

Calculator shows error because maximum value of inverse of sin function can be one.
