Drawing method:

straight line: (such as: 3 x - 2)

polynomial: (such as: x ^ 3 + 3 x ^ 2-5 x + 2)

trigonometric Function: sin(x), cos(x/2), tan(2x), csc(3x), sec(x/4), cot(x)

Anti-trigonometric Function: arcsin(x), arccos(x), arctan(x), arccsc(x), arcsec(x), arccot(x)

Exponentiation(e^x) and logarithm: ( Nature logarithms: ln(x) logarithms based on 10: log(x)

The absolute value: : such as abs(x)

Hyperbolic Function and anti-hyperbolic Function: sinh(x), cosh(x), tanh(x), arcsinh(x), arccosh(x), arctanh(x)

Sign (1 if the sign is positive, −1 if the sign of the function is negative. For example, try sign(sin(x)))

You can also plot math Function:

ceiling: ceil(x) and round: round(x)

square radical sqrt(x)

you can mix the Use the above Function such as: " ln (abs ( x)) ".

You must Use the rule to draw, Example I"2 tan x" can be drawn, but "tan 2x" cannot be drawn. You have to write it like this: "tan(2x)".
