I am sorry but I am quite new to Maxima.I have the following expression

Expression

And i was trying to set maxima to rearrange it with this

Substitution

My aim is for maxima to remove Vout and Vin completely in order to have a final expression with just VCR.

I did it "by hand" by dividing numerator and denominator by Vin^2. The result I got and that I wanted maxima to do it by himself was:

Expected Output

  • Good question. Since you know `VCR = Vout/Vin`, try `subst(Vout = VCR*Vin, eff_simp)` and then `ratsimp` on the result of that. Also, keep in mind it's easier for others to understand what's going on if you paste text expressions into the problem statement instead of linking images. – Robert Dodier Nov 30 '22 at 00:38
  • Thank you for your answer Robert, it did work! I did go around the subst() function for a while but it would always leave either Vin or Vout in the equation, depending on which it substituted. I didn't realize that ratsimp would do the trick, I thought it would just rearranje the equation but leave the Vin or Vout where it was. And sorry for the links, it was my first post here and I didn't understand why I couldn't post images. – Rodrigo Pinto Dec 01 '22 at 12:45
