Sorry, very simple question, but I really can't work it out... I want to use the output of a maximation for further calculations. something like: z[y_]=-y^2+y a=Maximize[z,{y}] b=Extract[a,1] Now mathematica returns {y -> -0.5}. I want to assign the value of -0.5 to a new variable. So far I haven't worked out how to do this (besides copy and paste!). Thanks for any comment.
