Given an expression ``f``, returns a list ``[f_1, f_2, ..., f_n]``, where:: f = f_1 o f_2 o ... f_n = f_1(f_2(... f_n)) Note: This is a General decomposition function. It also decomposes Polynomials. For only Polynomial decomposition see ``decompose`` in polys. Examples ======== >>> from sympy.abc import x >>> from sympy import decompogen, sqrt, sin, cos >>> decompogen(sin(cos(x)), x) [sin(x), cos(x)] >>> decompogen(sin(x)**2 + sin(x) + 1, x) [x**2 + x + 1, sin(x)] >>> decompogen(sqrt(6*x**2 - 5), x) [sqrt(x), 6*x**2 - 5] >>> decompogen(sin(sqrt(cos(x**2 + 1))), x) [sin(x), sqrt(x), cos(x), x**2 + 1] >>> decompogen(x**4 + 2*x**3 - x - 1, x) [x**2 - x - 1, x**2 + x] zexpecting Expr but got: `%s`rNcs |jvS)N) free_symbols)xsymboll/var/www/html/construction_image-detection-poc/venv/lib/python3.10/site-packages/sympy/solvers/decompogen.pyMs zdecompogen..)r isinstancerr TypeErrorr rrris_PowbaserExp1expargssubs decompogenr r list enumeratehas_freelenfuncrfiltergensr ValueError) frargrd0iadfpr$f1f2rrrr sR           rcCsPt|dkr |dS|d||d}t|dkr|St|g|dd|S)a0 Returns the composition of functions.
