The operations for equations are to be given as follows:
Addition: +, Subtraction: -, Multiplication: *, Division: /. power: pow(a, b) is ab. examples... ex is pow(e, x) x2 is pow(x, 2) sin, cos, tan: sin x is given as sin(x) cos x is given as cos(x) tan x is given as tan(x) sin-1, cos-1, tan-1: sin-1 x is asin(x) cos-1 x is acos(x) tan-1 x is atan(x) Constants: Π is pi or PI, e is e or E. Sample equation: for y = x2 -5x + 6 = 0, you have to give the equation: pow(x,2) - 5*x + 6 You can use brackets '()' to group operations.
