Manual

• The only allowed basic operators are addition (+), subtraction (-), multiplication (*), and division (/).
• Supported functions: sin(x), cos(x), tan(x), sqrt(x), exp(x, y), log(x), and ln(x).
  • The sin, cos, and tan input angle is in radian.
• No limitation on the number of inputted numbers, operators, and functions.
• For negative number, try to surround it with a bracket. For example, 1 - (-1) and (-cos(0)) + 2. Inputting an expression such as 1 - -1 might lead to unexpected result.
• Can show and delete the history of past calculations.
• Examples of valid expression:
  • 3 * 2 + 2 - 3 / 2
  • (2 + (1)) - (-3 ) *4
  • exp(exp(3, 2), (-2))
  • log(cos(0.01))*cos(0)+ln(ln(35)+80)-cos(sin(tan(7.85)))
