Need help to simplify a long equation. I used the simplify_full() function, but with no results. This is the equation:
VN1 == -((R2R3R4R5 + (R2R4R5 + R3R4R5)R1)RS3VBEMF2 - (R2R3R4R5 + (R2R4R5 + R3R4R5)R1)RS2VBEMF3 + (((R3R4R5 + R4R5R6)R1 + (R3R4R5 + R4R5R6)R2)L2L3s^2 + ((R3R4R5 + R4R5R6 + (R3R4 + R4R6)R2)L2L3s^3 + ((R3R4R5 + R4R5R6 + (R3R4 + R4R6)R2)L2RS3 + (R3R4R5R6 + (R3R4(R5 + R6) + R4R5R6)R2)L2 + (R2R3R4R6 + R3R4R5R6 + (R2R4R6 + R4R5R6)R1 + (R3R4R5 + R4R5R6 + (R3R4 + R4R6)R2)RS2)L3)s^2 + (R2R3R4R5R6 + (R2R4R5R6 + R3R4R5R6)R1 + (R3R4R5R6 + (R3R4(R5 + R6) + R4R5R6)R2)RS2 + (R2R3R4R6 + R3R4R5R6 + (R2R4R6 + R4R5R6)R1 + (R3R4R5 + R4R5R6 + (R3R4 + R4R6)R2)RS2)RS3)s)L1 + (R2R3R4R5R6 + (R3R4R5 + R4R5R6 + (R3R4 + R4R6)R2)L2L3s^2 + (R2R4R5R6 + R3R4R5R6)R1 + (R3R4R5R6 + (R3R4(R5 + R6) + R4R5R6)R2)RS2 + (R2R3R4R6 + R3R4R5R6 + (R2R4R6 + R4R5R6)R1 + (R3R4R5 + R4R5R6 + (R3R4 + R4R6)R2)RS2)RS3 + ((R3R4R5 + R4R5R6 + (R3R4 + R4R6)R2)L2RS3 + (R3R4R5R6 + (R3R4(R5 + R6) + R4R5R6)R2)L2 + (R2R3R4R6 + R3R4R5R6 + (R2R4R6 + R4R5R6)R1 + (R3R4R5 + R4R5R6 + (R3R4 + R4R6)R2)RS2)L3)s)RS1 + (R2R3R4R5R6 + (R2R4R5R6 + R3R4R5R6)R1)RS2 + (R2R3R4R5R6 + (R2R4R5R6 + R3R4R5R6)R1 + ((R3R4R5 + R4R5R6)R1 + (R3R4R5 + R4R5R6)R2)RS2)RS3 + (((R3R4R5 + R4R5R6)R1 + (R3R4R5 + R4R5R6)R2)L2RS3 + (R2R3R4R5R6 + (R2R4R5R6 + R3R4R5R6)R1)L2 + (R2R3R4R5R6 + (R2R4R5R6 + R3R4R5R6)R1 + ((R3R4R5 + R4R5R6)R1 + (R3R4R5 + R4R5R6)R2)RS2)L3)s)IC1 + (((R2R3R4 + R3R4R5 + (R2R4 + R3R4 + R4(R5 + R6))R1)L3VBEMF2 - (R3R4R5 - R2R4R6)L2VBEMF3)s^2 + ((R2R3R4 + R3R4R5 + (R2R4 + R3R4 + R4(R5 + R6))R1)RS3VBEMF2 + (R2R3R4(R5 + R6) + (R2R4(R5 + R6) + R3R4(R5 + R6))R1)VBEMF2 + (R2R3R4R6 + (R2R4R6 + R3R4R6)R1 - (R3R4R5 - R2R4R6)RS2)VBEMF3)s)L1 + ((R2R3R4 + R3R4R5 + (R2R4 + R3R4 + R4(R5 + R6))R1)RS3 ...
Suggestions. Think of a shorter title, maybe "Need help to simplify a long equation". Make your current title the first sentence in your question. Format your equation either by indenting it four spaces, or by selecting it and clicking the "code" button (the one with '101 010').
What kind of simplification do you expect ?
what kind of simplification you are looking for is not clear. I can see lots of variables like R1, R2, R3...S1, S2, S3... we need to know how you want to simplify this further.
First try
expand()
Sometimes it gives the 'simplification' you expected.Well, i need a simplification which gives me a fraction, and specify which is the numerator and denominator. Also, i want to reduce the number of variables to be regrouped. I want something like in example below : expr = x/(x^2 + x)
expr.simplify_full()
1/(x + 1)
Thank you! :)
