# What is your favourite unusual integration technique

Hello everyone,,

Any one tell me some unusual or advanced integration techniques, I am already familiar with the standard ones like u-substitution, integration by parts, trig substitution, partial fractions, Feynman technique (differentiation under the integral), integrating the inverse, Laplace transforms In the integral and matrix inversion so I was wondering if anyone knew some rare ones (definite or indefinite)

Please do not answer with any already listed Otherwise Any help is appreciated Thanks in advance

Edit: thanks for the answers Ps: my favourite it integrating the inverse and the Feynman technique
