JSFHMaple FundamentalsLast revision: October 4, 2010JSFHThis tutorial is intended for beginning Calculus students. It is by no means a comprehensive introduction to maple. The purpose of this document is to help you get started on maple, become familiar with the basic maple commands, and solve elementary tasks with the help of maple. Maple was developed at the University of Waterloo in Ontario, Canada, hence the name and the leaf symbol.Maple operates in the worksheet mode or in the document mode (default). Much of this tutorial is written in the document mode, as indicated by the red > symbol on the left. Occasionally we will switch to the document mode.
<Text-field style="Heading 1" layout="Heading 1">Basics</Text-field>Maple is a computer algebra system. Unlike the standard graphing calculator it will attempt to give answers in symbolic form, rather than finding decimal approximations. Example: Compute LUklbXJvd0c2Iy9JK21vZHVsZW5hbWVHNiJJLFR5cGVzZXR0aW5nR0koX3N5c2xpYkdGJzYmLUkjbWlHRiQ2I1EhRictRiM2JUYrLUkmbXNxcnRHRiQ2Iy1GIzYkLUkjbW5HRiQ2JFEiOEYnLyUsbWF0aHZhcmlhbnRHUSdub3JtYWxGJ0Y6RjpGK0Y6 .sqrt(8);sqrt(8.0);In the first case maple simplified the result. When given a decimal input maple gave a decimal output in the second case.Like any other programming language there are some rules which you need to follow. Here are some of themEvery command line must end with a semicolon. You may substitute a colon if you want to suppress the output.Maple is case-sensitive, X and x mean different things.A * for multiplication is required. This is different from graphing calculators were you can enter 2x. In maple 2*x is required.You can use the # symbol for comments at the end of a command line (after the semicolon).You may use % to refer to the last executed expression.In 2-d input (default) you can get away without the semicolon and without the multiplication *. But be careful, even there the * is required in certain situations.Illustrations:sqrt(5)*sqrt(20); # multiply two rootsX-x;X-x: # output suppressed%; # use of %2x; # missing *2*x;Here we show now work in the document mode. You can even use some symbols from the expression tab on the left.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print(); # input placeholderLUklbXJvd0c2Iy9JK21vZHVsZW5hbWVHNiJJLFR5cGVzZXR0aW5nR0koX3N5c2xpYkdGJzYpLUkjbWlHRiQ2I1EhRictSSZtc3FydEdGJDYjLUYjNiUtSSNtbkdGJDYkUSI1RicvJSxtYXRodmFyaWFudEdRJ25vcm1hbEYnLyUrZXhlY3V0YWJsZUdRJmZhbHNlRidGOEYrLUYjNiZGKy1GMDYjLUYjNiUtRjU2JFEjMjBGJ0Y4RjtGOEY7RjhGK0Y7Rjg=print(); # input placeholderLUklbXJvd0c2Iy9JK21vZHVsZW5hbWVHNiJJLFR5cGVzZXR0aW5nR0koX3N5c2xpYkdGJzYoLUkjbW5HRiQ2JFEiMkYnLyUsbWF0aHZhcmlhbnRHUSdub3JtYWxGJy1JI21vR0YkNi1RIn5GJ0YvLyUmZmVuY2VHUSZmYWxzZUYnLyUqc2VwYXJhdG9yR0Y4LyUpc3RyZXRjaHlHRjgvJSpzeW1tZXRyaWNHRjgvJShsYXJnZW9wR0Y4LyUubW92YWJsZWxpbWl0c0dGOC8lJ2FjY2VudEdGOC8lJ2xzcGFjZUdRJjAuMGVtRicvJSdyc3BhY2VHRkctSSNtaUdGJDYlUSJ4RicvJSdpdGFsaWNHUSV0cnVlRicvRjBRJ2l0YWxpY0YnLUYzNi1RIjtGJ0YvRjYvRjpGUEY7Rj1GP0ZBRkNGRS9GSVEsMC4yNzc3Nzc4ZW1GJy8lK2V4ZWN1dGFibGVHRjhGLw==print(); # input 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print(); # input placeholderLUklbXJvd0c2Iy9JK21vZHVsZW5hbWVHNiJJLFR5cGVzZXR0aW5nR0koX3N5c2xpYkdGJzYrLUkobWZlbmNlZEdGJDYkLUYjNictSSNtaUdGJDYlUSJ4RicvJSdpdGFsaWNHUSV0cnVlRicvJSxtYXRodmFyaWFudEdRJ2l0YWxpY0YnLUkjbW9HRiQ2LVEoJm1pbnVzO0YnL0Y4USdub3JtYWxGJy8lJmZlbmNlR1EmZmFsc2VGJy8lKnNlcGFyYXRvckdGQi8lKXN0cmV0Y2h5R0ZCLyUqc3ltbWV0cmljR0ZCLyUobGFyZ2VvcEdGQi8lLm1vdmFibGVsaW1pdHNHRkIvJSdhY2NlbnRHRkIvJSdsc3BhY2VHUSwwLjIyMjIyMjJlbUYnLyUncnNwYWNlR0ZRLUkjbW5HRiQ2JFEiMUYnRj4vJStleGVjdXRhYmxlR0ZCRj5GPi1GLDYkLUYjNidGMEY6LUZVNiRRIjJGJ0Y+RlhGPkY+LUY7Ni1RIjtGJ0Y+RkAvRkRGNkZFRkdGSUZLRk0vRlBRJjAuMGVtRicvRlNRLDAuMjc3Nzc3OGVtRictRjs2LVEifkYnRj5GQEZDRkVGR0ZJRktGTUZfby9GU0Zgb0Zjby1GOzYtUSIjRidGPkZARkNGRUZHRklGS0ZNRl9vRmZvLUYxNiVRNX53aXRob3V0fnRoZX4mIzg5MDE7RidGNEY3RlhGPg==print(); # input placeholderThere is a host of maple commands, built-in functions and the like.

The evalf command comes in handy when you look for numerical values rather than symbolic answers.Example: Solve the equation 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.Note that for equations we use the simple = sign, and not :=. Let's first use solve in this problem.solve( x^3 + x + 1 = 3*x^2,x);maple gives symbolic answers. We can get decimal conversions with evalfevalf(%);Numerical answers can also be obtained directly with the fsolve commandfsolve( x^3 + x + 1 = 3*x^2,x);Example: Solve the equation 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 .We know that this equation has infinitely many solutions, maple selects a few. First we define the equation as Eqn, and then we solve it with solve.Eqn := sin(x) = sin(2*x);solve(Eqn, x);evalf(%);fsolve for the same problem results in fsolve( Eqn , x);fsolve employs a numerical method and it singles out just one solution. But fsolve also lets you select a search interval or an initial point. If we want solutions in the interval [1,3] we enterfsolve(Eqn,x=1..3);A solution near LUklbXJvd0c2Iy9JK21vZHVsZW5hbWVHNiJJLFR5cGVzZXR0aW5nR0koX3N5c2xpYkdGJzYmLUkjbWlHRiQ2JVEieEYnLyUnaXRhbGljR1EldHJ1ZUYnLyUsbWF0aHZhcmlhbnRHUSdpdGFsaWNGJy1JI21vR0YkNi1RIj1GJy9GM1Enbm9ybWFsRicvJSZmZW5jZUdRJmZhbHNlRicvJSpzZXBhcmF0b3JHRj0vJSlzdHJldGNoeUdGPS8lKnN5bW1ldHJpY0dGPS8lKGxhcmdlb3BHRj0vJS5tb3ZhYmxlbGltaXRzR0Y9LyUnYWNjZW50R0Y9LyUnbHNwYWNlR1EsMC4yNzc3Nzc4ZW1GJy8lJ3JzcGFjZUdGTC1JI21uR0YkNiRRIjVGJ0Y5Rjk= can be found byfsolve(Eqn,x=5);Example: Find the inverse function of 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 .

Rule of thumb: either you mention x with f(x) and the range, or you don't include x at all. These commands do not mix.The graphs usually come out fairly large in maple. It is recommended to manually resize them so that you will save on paper. Use the print previewer (fifth icon from the left) for your decision.Now let's add some bells and whistles to the graph.view(x-range, y-range) sets the viewing area just like on a graphing calculator.thickness controls the thickness of the curvecolor sets the color (duh)title let's you include a titlenumpoints: a high number will refine the graph and take out unwanted cornersdiscont=true will allow for jumps in the graph.scaling=constrained will use the same length units on the x- and the y-axis (square option on a graphing calculator).Much of this can be done by selecting the Plot Builder option.Example: Graph the function 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f := x -> (x^2+1)/(x-1);plot(f,-2..5,view=[-2..5,-3..10], discont=true,color=blue,thickness=2,title=`what a graph...`,numpoints=5,scaling=constrained);The noticeable corners are caused by selecting a very small value in numpoints (bad idea).If you want to display several functions in a common picture you need to enclose the functions in a common bracket.
