How do you find the integral of #sinpixcospix dx#?
For this integral, you should recall that
In your case, instead of
The integral becomes
Recalling the relation between
One method gives correct answer:
A different method gives an answer that looks different:
Since d(sin t) =cos t dt, substitution will work:
The answer look different, but what is the difference?
Hint: subtract and simplify.
The difference is a constant! The two solutions have different
