Dear all, I have a fairly simple question that i was not able to figure out on mathematica. I have function KI with two variables gama and teta. Gama varies over a predefined range for which the values are input. Then I take the derivative of KI with respect to teta "AA" as gama varies. So I obtain a list of expressions for AA {...,.....,....} as gama varies in the range. Last thing I do is try to solve each element AA with respect to teta. I thought this would give me a list of teta solutions {.,..}. But i have an empty set. On the other hand when i define gama as a single variable not over a range. Solution is found for teta. How do I input each element of AA into the solver? (i.e. see below for the simplified code) gama=Range[ ......] KI(teta,gama) AA=Diff(KI,teta) solve(AA,teta) Best, Uno.
