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?

Use multiple tests, so if you want to check if an input number is odd and between 32 and 45: Code: if ((inputNum%1) && (inputNum>=32) && (inputNum<=45)) printf("Valid!\n");
