![]() Do the same at x = -1 and some other points. Let f(x) = sqrt(x + 2) and g(x) = x, input functions f and g and press on the button "(f * g)(x)".Explore the graph (in red) of function (f * g)(x) is it what is expected? Compare the zeros of f, g and f * g and explain. Let f(x) = x - 2 and g(x) = x, input functions f and g and press on the button "(f * g)(x)".Is it the intersection of the domains of f and g? Do the same at x = 3 and some other points. Let f(x) = sqrt(x-2) and g(x) = x, input functions f and g and press on the button "(f - g)(x)".Explore the graph (in red) of function (f - g)(x) is it what is expected?.Let f(x) = x + 1 and g(x) = x, input functions f and g and press on the button "(f - g)(x)".Explore the domain of f + g graphically.Explore the graph (in red) of function (f + g)(x) take some specific values of x if necessary at x = 1 for example.Let f(x) = sqrt(x) and g(x) = x, input functions f and g and press on the button "(f + g)(x)".Some tutorials and activities are suggested here but the use of this graphing calculator to explore and gain deep understanding of operations on functions is unlimited and any suggestions are welcome. Hover the mousse cursor on the top right of the graph to have the option of downloading the graph as a png file, zooming in and out, shifting the graphs. Hover the mousse cursor over the graph to trace the coordinates. Use the small letter x for the variable in the expressions of functions f and g. (see more details on each operation below). Five operations are supported by this calculator. How to Use The Operations on Functions CalculatorĮnter formulas for functions f and g and press the button corresponding to the operation to be carried out on functions f and g and explore the graphs of the three functions: f (in blue), g (in green) and the graph of function due to the operation carried out on f and g (in red). If needed, Free graph paper is available. Also the argument of a function must be writtwn between brackets. NOTE: The multiplication operator * must be used explicitly whenever there is multiplication. Here is a comprehensive list of basic functions and operators that may be used.Įxamples of formulas for functions f and g, that you may copy and paste to use as inputs, are shown below: Algebraic as well as trigonometric, inverse trigonometric, exponential, logarithmic and hyperbolic functions may be used as input function. The calculator has two inputs: one for function f and a second one for function g. a pollution of 1 gram of benzene in a certain amount of water converts to N A/78.11≈ 7.Operations on Functions - Graphing CalculatorĪn online graphing calculator to carry outįive operations are supported by this calculator: addition, subtraction, multiplication, division and Using the above calculator you could find that e.g. Or 1 mole of a substance will contain Avogadro's number of that substance. The term " mole" is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram. ![]() It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu".Īlso, important in this field is Avogadro's number (N A) or Avogadro's constant (6.0221 x 10 23). ![]() In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. Molecular mass or molar mass are used in stoichiometry calculations in chemistry. This Calculator has been tested on Internet Explorer version 6 only,įirefox might not show all fields correctly.

Lenntech BV cannot be held responsible for errors in the calculation, Make sure you enter the molecule of crystallization at last (e.g. ![]() The calculator handles at most two different bracket levels. The molecular mass calculator will recognize the entered formula's, which are included in the list of organic compounds. ![]() Or you can choose by one of the next two option-lists, which contains a series of common organic compounds (including their chemical formula) and all the elements. This online calculator you can use for computing the average molecular weight (MW) of molecules by entering the chemical formulas (for example C3H4OH(COOH)3 ).
