The x=f(a) and y=f(a)input string specifies the expression to be evaluated.  Each expression is a function of variable "a".  The "a min" and "a max" field are the bounds between which the curve is drawn. "#points" is the number of points used to build the curve. Depress the "Go" button to draw the curve.

The expression supports arithmetic, logical and conditional operators. They are:

(unary) !, -

(binary) +, -, *, /, %, <, > <=, >=, ==, != ,&&, ||

(ternary) ? :

The ternary operator is a conditional operator. For example, a ? b : c evaluates to b if a != 0, and to c if a==0.

Operands can also be numeric constants (e.g. 1.0), pre-defined named constants, or pre-defined functions.

The named constants are:

MAXFLOAT

MINFLOAT

M_E

M_LOG2E

M_LOG10E

M_LN2

M_LN10

M_PI

M_SQRT2 = sqrt(2)

M_SQRT1_2 = sqrt(1/2)

Most of the pre-defined functions come from the math library:

cos, sin, tan,

acos, asin, atan, atan2,

cosh, sinh, tanh,

sqrt, pow, exp, log, log10,

ceil, floor, fabs, fmod.

Other functions are:

rand(f) - Random number generator
