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) Logarithm to base 10: 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:

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

Square rootsqrt(x)

You can mix and match the above functions like:ln(abs(x))".

You have to use the rules to plot, for example I "2 tan x" is plottable but "tan 2x" is not. You have to write it like this: "tan(2x)".
