 (a1 q1^2 + b1 p1^2 + c1 q1 + d1 p1 + e1) E^(a2 q1^2 + b2 p1^2 + c2 q1 + d2 p1 + e2)


Is there a command to select factor polynomial



(a1 q1^2 + b1 p1^2 + +c1 q1 + d1 p1 + e1)


and exponent of E



(a2 q1^2 + b2 p1^2 + c2 q1 + d2 p1 + e2)

            You can use Exponent and Coefficient as follows:



            exp = (a1 q1^2 + b1 p1^2 + c1 q1 + d1 p1 + e1) E^(a2 q1^2 + b2 p1^2 + c2 q1 + d2 p1 + e2);

            Exponent[exp, E]



            e2 + d2 p1 + b2 p1^2 + c2 q1 + a2 q1^2




            Coefficient[exp, E, Exponent[exp, E]]



            e1 + d1 p1 + b1 p1^2 + c1 q1 + a1 q1^2

                              One-line joke

                              A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain.
