the integral value is 0

Answer 2

Answer:

0

Step-by-step explanation:

This question is for the king property. Let this integration be I. Then replace x with (pie-x) then you will find exponential as it is but when you will put (pie-x) into cubic of cos then it comes out negative because cos{(2n+1)pie-somthing} =-cos(something) so it will be - cos^3{(2n+1)x} you find I is equal to it's minus. Ao 2I becomes 0 then I will be zero.. Pls tick it as a brainist answer
