Webb6 apr. 2024 · A couple notes about the code above: we define symbols using real=True because it enables some trigonometric simplifications that SymPy won’t apply if it thinks variables might be complex numbers (which is the default assumption). Also we provide sympy.solve the options dict=True and simplify=True – the former provides the … Webb29 juli 2024 · With the help of sympy.log () function, we can simplify the principal branch of the natural logarithm. Logarithms are taken with the natural base, e. To get a logarithm of a different base b, use log (x, y), which is essentially short-hand for log (x) / log (y). Syntax : sympy.log () Return : Return the simplified mathematical expression.
