I also recommend using cos(t) instead of cos(1.0*t) , as SymPy will see them as different (e.g., cos(t) - cos(1.0*t) …

3.3.2: Simplifying Trigonometric Expressions using Sum and …

WebJan 31, 2024 · 1 I have an expression like this calculated by Sympy: -1.0*pi* (-1.0*sin (1.0*t) - 0.025*cos (1.0*t) + 4.0*cos (2.0*t)) Then I try a lot of options provided for the simplification of expression but they don't work too much. When I use expand_trig (), it returns: pi* (1.0*sin (1.0*t) + 0.025*cos (1.0*t) - 4.0*cos (2.0*t)) WebMay 5, 2011 · You should look into ChebyshevT polynomials. It has the property that ChebyshevT [3, Cos [th] ]==Cos [3*th]. So for your problem the answer is In [236]:= x/2 + ChebyshevT [3, x/2] Out [236]= -x + x^3/2 Alternatively, you could use TrigExpand: new homes for sale in henrico va
