A. Using Online Full Screen Scientific Calculator

Important! this math or scientific calculator uses [DEG] mode or degree mode. This used for trigonometric calculation. For example cos (90) the same as cos 90°. [DEG] mode commonly used by students all over the world.

Be careful performing trigonometric calculations with a scientific calculator. Some calculators use RAD Mode or Radian (1 RAD = 57,296°) as a standard-setting. [RAD] mode, commonly used at higher education, for example, pure physics. Click [RAD] to change Radian Mode.
