# sympy.integrals.transforms.sine_transform() in python

• Last Updated : 10 Jul, 2020

With the help of sine_transform() method, we can compute the sine transformation by getting the transformed function by using this method.

Sine transformation

Syntax : sine_transform(f, x, k, **hints)

Return : Return the transformed function.

Example #1 :

In this example we can see that by using sine_transform() method, we are able to compute the sine transformation and returned the transformed function.

## Python3

 `# import sine_transform``from` `sympy ``import` `sine_transform, exp``from` `sympy.abc ``import` `x, k, a`` ` `# Using sine_transform() method``gfg ``=` `sine_transform(x ``*` `exp(``-``a ``*` `x``*``*``2``), x, k)`` ` `print``(gfg)`

Output :

sqrt(2)*k*exp(-k**2/(4*a))/(4*a**(3/2))

Example #2 :

## Python3

 `# import sine_transform``from` `sympy ``import` `sine_transform, exp``from` `sympy.abc ``import` `x, k, a`` ` `# Using sine_transform() method``gfg ``=` `sine_transform(x ``*` `exp(``-``a ``*` `x``*``*``2``), x, ``4``)`` ` `print``(gfg)`

Output :

sqrt(2)*exp(-4/a)/a**(3/2)
