I have posted the question just as it was given.

Isn't the expectation value supposed to be ∫f* cos4x f dx

It is possible. The above question is from a previous year entrance test.

Could you please explain or suggest a source from which I can understand the difference.

Thank you, sir. I will slowly start exploring all these sections.
