function graphing calculator
you can graph three functions simultaneously:
click "− o + ← ↑ ↓ →" to move the image!
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)".
