What is the difference between DEG and RAD in calculators?
In: Mathematics
DEG is for when you want to do calculations using degrees and RAD is for when you want to do calculations using radians. Switching between the two is useful when using trigonometric functions. So if you’re in DEG and put SIN(30), you’ll get 0.5 since it’s calculating the sine of 30 degrees. If you’re in radians and put SIN(30), it will calculate sine of 30 radians, which should be something close to -1.
The conversion between the two systems is knowing 180 degrees = 1 pi radians.
