rtW` in solveset. We can implement this using bivariate.py , right ? But it is handled through list and old methods.If we want this in solveset then need some good changes in file (or need to rewrite). Please share your thinking regarding this. Thanks. -- Shekhar Prasad Rajak On Thursday, 4 Febru

You can use this : a,b,c = symbols('a b c') expr = 49*cos(x)**2+49*sin(x)**2 + 5 expr.replace(a*sin(b)**2+a*cos(b)**2, a, exact=True) # output 49*sin(x)**2 + 49*cos(x)**2 + 5 On Thursday, 18 February 2016 15:14:00 UTC+5:30, Paul Royik wrote: > > I'm trying to simplify a*cos(b)**2+a*sin(b)**2

about radical solver in sympy docs ,Please anyone share a link regarding this. Right now solveset can handle single equation for a single variable, in any domain either real or complex. So there is need of non linear system in solveset ,isn't it ? or using old solve for solving non linear system?
