distribution of a squart

Posted 9 years ago

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?

Please see the attached notebook. I wasn't able to get the Pi^2 under the radical, though.
