Put the calculator in Radian mode. If you are calculating sin30 you should be in degree mode as your angle 30 is measured in degrees. But if your calculator is in degree mode or you are using a function that outputs in degrees it does the conversion the multiplication by 180 for you and you will get an answer in degrees.

You can also convert Degree to radian if needed. When you want to graph a trig function you should be in radian mode. Eg if you enable the DEG mode and type sin 30 the calculator will assume 30 to be 30 degrees and return 05 as answer.

You only really need to change from radians to degrees or vice versa when an equation involves an angle for example sine and cosine ect i dont see why you would need to change for logs or exponentials. Enter the number of degrees. Should my calculator be in radians or degrees for sohcahtoa.

If its unspecified and a shows up you should assume radians. If necessary press 2ndMODE to access the Home screen. Press ENTER to convert the degree measure to radians.

It depends whether the question gives the angles in degrees or radians. In contexts where you think your professor has simplified by opting to not use the degree symbol some general rules of thumb can be applied. Should my calculator be in radians or degrees for sohcahtoa.
