I already turned in this code, but was trying to figure out for myself:

Code:

{
//arcsine
cout << "Enter a degree to calculate for arcsine: (Choice should be between -1 and 1.) ";
cin >>num1;
result = asin (num1) * 180.00 / pi;
if (num1 >= -1)
{
cout << " The arcsine of " << num1 << " comes out to be " << result << " degrees." << endl;
}
else
{
cout << "Your choice is uncomputable in this equation. \n";
}
}

I have it so there is an error if your input is greater than 1, but I cannot figure out how to do it to set if your input is lower than negative 1 at the same time- How do I set two boundaries at once?
