Python | sympy.integrate() method Last Updated : 12 Jun, 2019 Comments Improve Suggest changes Like Article Like Report With the help of sympy.integrate() method, we can find the integration of mathematical expressions in the form of variables by using sympy.integrate() method. Syntax : sympy.integrate(expression, reference variable) Return : Return integration of mathematical expression. Example #1 : In this example we can see that by using sympy.integrate() method, we can find the integration of mathematical expression with variables. Here we use symbols() method also to declare a variable as symbol. Python3 1=1 # import sympy from sympy import * x, y = symbols('x y') gfg_exp = sin(x)*exp(x) print("Before Integration : {}".format(gfg_exp)) # Use sympy.integrate() method intr = integrate(gfg_exp, x) print("After Integration : {}".format(intr)) Output : Before Integration : exp(x)*sin(x) After Integration : exp(x)*sin(x)/2 - exp(x)*cos(x)/2 Example #2 : Python3 1=1 # import sympy from sympy import * x, y = symbols('x y') gfg_exp = sin(x)*tan(x) print("Before Integration : {}".format(gfg_exp)) # Use sympy.integrate() method intr = integrate(gfg_exp, x) print("After Integration : {}".format(intr)) Output : Before Integration : sin(x)*tan(x) After Integration : -log(sin(x) - 1)/2 + log(sin(x) + 1)/2 - sin(x) Comment More infoAdvertise with us Next Article Python | sympy.integrate() method J Jitender_1998 Follow Improve Article Tags : Python SymPy Practice Tags : python Similar Reads Python | sympy.Integral() method With the help of sympy.Integral() method, we can create an unevaluated integral of a SymPy expression.
