There is often an indicator of units written right up with the numerals to let you know what you're getting. To change to degrees, look for a MODE key. However, if you get -0.988 then your calculator is set to radian mode. Would you like to test our apps Click here to download our free trials. If you get 0.5 using one of these methods, then you know which works. Shop Stanford University Calculators & Batteries at the Cardinals Bookstore. eCalc is a free and easy-to-use online scientific calculator that supports and resembles a ti-30 with many advanced features, including unit conversion, equation solving, square. The learning center for future and novice engineers. Enter 30 and then SIN and see if you get 0.5. The educational resource for the global engineering community. How do you test this: Remember the sine of a 30-degree angle is 0.5. Then, you need to determine whether you enter the angle (check the units) and then sin, cos, tan, etc., or whether you press the sin, cos, etc., button and then enter the number.
