Hi, i would like to know which function can i use in Mathematica to have a distribution of an expression? for example:
I don't want to have any brackets (in an other meaning, a command that give the opposite of "simplify" command) thanks.
I have this fonction? f1=Sin[b??(-m^2/a^2 +(m?(k_? ))/ab)]
I want to distribute "b ? " into the square to obtain:
f1=Sin?(-b^2?^2m^2/a^2 +b^2?^2(m?(k_? ))/ab)
After I suppose??=a/b
I will have:f1=Sin?(-?^2m^2/?^2 +?^2(m?(k_? ))/?)
My question is : is there a command in mathematica that can give me this result?
In:= Expand[Cos[(x + y)^2]]
Out= Cos[(x + y)^2]
In:= Map[Expand, Cos[(x + y)^2], 1]
Out= Cos[x^2 + 2 x y + y^2]
when I have an expression with cosinus or sinus [ex. b²(1/b²t+cos(b²(s/t²+k/t²))] the "expand" command does not expand terms in brackets after cosinus. How can I do to expand this part?
