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.
# 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 :
# 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)
