drawing method:

straight line: (like:3x − 2)

polynomial: (like:x^3 + 3x^2 − 5x + 2)

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

inverse trigonometric functions: arcsin(x), arccos(x), arctan(x), arccsc(x), arcsec(x), arccot(x)

index(e^x)andlogarithm： (natural logarithm: ln(x) base 10 logarithm: log(x)

absolute value::such as abs(x)

hyperbolic and inverse hyperbolic functions: 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 mathematical functions like this:

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

square rootsqrt(x)

you can mix the above functions like: "ln(abs(x))".

you have to use rules for plotting, for example i "2 tan x" can be plotted, but "tan 2x" cannot be plotted. you have to write it like this: "tan(2x)".
