With the help of sympy.replace() method, we can replace the functions in the mathematical expression without editing the whole expression by using sympy.replace() method.
Syntax :
sympy.replace()
Return : Return the replaced values in the mathematical expression.
Example #1 :
In this example we can see that by using sympy.replace() method, we are able to replace the mathematical functions in the expression and return the updated expression.
# import sympy from sympy import * x, y = symbols('x y') f = sin(x) + cos(2 * x) # Use sympy.replace() method gfg = f.replace(cos, sin) print(gfg) |
Output :
sin(x) + sin(2*x)
Example #2 :
# import sympy from sympy import * x, y = symbols('x y') f = log(sin(x)) + tan(cos(2 * x)) # Use sympy.replace() method gfg = f.replace(log, tan) print(gfg) |
Output :
tan(sin(x)) + tan(cos(2*x))
