This calculator is developed for graphing complicated functions, including logarithmic, exponential, trigonometric, hyperbolic. To plot function one should enter a mathematical expression with x as an unknown variable, as well as the minimum and maximum of X-axis and the number of points.
The list of functions that one can use:
exp - exponential function sqrt - square root abs - absolute value of a number (module) ln - natural logarithm (logarithm to the base e) lg, log10 - common logarithm (logarithm to the base 10) log2 - binary logarithm (logarithm to the base 2)
sin - sine cos - cosine tg, tan - tangent ctg, cot - cotangent
ceil - returns the smallest integer greater than or equal to argument floor - returns the largest integer less than or equal to argument round - round a number to the nearest integer trunc - discards the fractional part of a number
Example of the expression: x ^ 2 - cos (arcsin (x)) * log2 (4) * abs (-PI * x)
