Using Matlab to Restrict the Domain You can your calculator or a software program such as MATLAB to restrict the domain so that the range is restricted to [−5, 5]. syms x f=x ∗( x+2) ∗( x −2) ; s o l=s o l v e ( f −5,x ) ; double ( s o l ) s o l=s o l v e ( f +5,x ) ; double ( s o l ) ans = 2.4567 ans = −2.4567 David Arnold (CR) Using TIKZ November 20, 2010 14 / 24
The Ideal Domain Use the results from MATLAB to set domain=-2.4567:2.4567. \ b e g i n { t i k z p i c t u r e } \ draw [ h e l p l i n e s ] (−5,−5) g r i d ( 5 , 5 ) ; \ draw [ t h i c k ,] ( −5 ,0) −−(5,0) node [ r i g h t ] {$ x $ } ; \ draw [ t h i c k ,] (0 , −5) −−(0,5) node [ above ] {$ y $ } ; \ draw [ t h i c k , blue , domain=-2.4567:2.4567 ] p l o t (\ x , { \ x ∗(\ x+2) ∗(\ x −2) }) ; \ end { t i k z p i c t u r e } Recompile workshop10.tex and note the difference.
