(sqrt(3)/3*cos(x)+1/3*sin(x))
the resulting expression should be:
2/3*cos(pi/6-x)
.simplify_full(), trig_reduce(), or simplify_trig() cannot produce this simplification.
Is sage currently capable of doing this?rtcFri, 21 Oct 2016 17:45:00 +0200https://ask.sagemath.org/question/35213/Sage fails to evaluate this expression.https://ask.sagemath.org/question/26372/sage-fails-to-evaluate-this-expression/Sage doesn't seem to compute correctly `8*sin(pi/9)^3 - 6*sin(pi/9) + 3^(1/2)` which is plain zero.xiver77Sun, 29 Mar 2015 11:12:06 +0200https://ask.sagemath.org/question/26372/
