Unformatted text preview: ( È l r 1 $ B ( B .B Þ cos 1 In Maple, “ ” yields int(x^(1/3)*cos(7*Pi*x),x=0. .1); # ( m ( # M # ( " ß ß ( %* Ð"Î$Ñ Ð#Î$Ñ Ð&Î'Ñ Ð"Î$Ñ Ð#Î$Ñ Ð#Î$Ñ #" $ "" " ) ) ' # Ð&Î'Ñ Š ‹ È ˆ ‰ 1 1 1 LommelS . (Do you know what the LommelS1 function is? Look it up in the Maple help.) To get the value this computes to (within a high degree of accuracy), put the offending code inside the function. Taking the above example and “evalfing it” (i.e., writing evalf “ ”) yields evalf( int(x^(1/3)*cos(7*Pi*x),x=0. .1);0.7934529806e2 , which will be more useful for purposes of, say, graphing. It may even be better to use “ instead of “ ” — note the capital I on the integration evalf( Int( evalf( int( ” command. This tells Maple to evaluate the integral numerically rather than to symbolically compute it and then evaluate the resulting formula. Oh yes, don't forget that in Maple is , not . 1 Pi pi...
