• Generals

• run Maple
1. Open a terminal using PuTTy, and connect to grendel.ece.ncsu.edu
2. setenv DISPLAY 152.14.92.29:0.0
3. run X in local window machine
• 2D math mode
• Use the Backspace and Delete keys to correct typing errors. Don't forget the semicolon - every command ends with a semicolon.
• restart clears all of Maple's former memory including errors and allows you to start afresh
• eval evaluate an expression with specific values, eval( 3*x*ln(x^3), x=r^(1/3));
• evalf evaluate using floating-point arithmetic, evalf( exp( Pi^2 ) );
• with load a Maple package, with( DEtools ); with( plots ):
• x := 4; diff( sin(x), x ); --> Error, x := 'x'; use quote key right of semicolon key, this clears value of x
• To refer to the output of the previous computation use %, % Most recent, %% Second most recent, %%% Third most recent
• { } is used in lists of functions, equations or variables where order of listing is unimportant, as in solve( {x + y = 1, 2*x + 7*y =0}, {x,y} );
• [ ] is used in ordered lists as in vector [1,2,3]

• Command

• diff( sin(x^2), x); - differentiation
• int( sin(x), x= 0..Pi ); int( a*x^2, x ); - integration

• Solve

• solve( {x + y = 1, x^2 - y = 1}, {x,y} );
mysolns := allvalues(%, 'd'); use quotation mark right of semicolon key. Recall that % refers to the result of the previous computation. (Be careful about the d - see what happens if you drop it, or try ?allvalues). Of these solutions, we want the one for which x,y are positive, so we approximate these solutions using
evalf( mysolns, 4 );
• fsolve attempt to obtain the approximate solutions. fsolve( 7*cos(x) + x + x^2 = 15, {x}, x=3..4 );

• Plot

• plot( x^2, x=-1..1 );
• Plotting Planar Curves: Planar curves are given in one of the three forms - explicitly as in (a parabola), implicitly as in (a circle), or in parametric form as in , (a cycloid). Curves may also be given in polar form as in the three leaved rose. To draw two explicitly given curves and y=1-2x over the interval [0,1], use plot( {x-x^2, 1-2*x}, x=0..1 );

• Matrix

• insert matrix
1. expand 'matrix' in the left menu
2. drag choose and select dimension
3. assign type, shape and data type
4. insert matrix
5. right click the matrix in main window and choose operation (inverse, eigenvalues and etc)
