Disclaimer: This example is not mine. I have chosen it from some book. I have also given the due reference at the end of the post.
So here is my example.
According to Stroud and Booth (2013)*, “By writing as , obtain a reduction formula for
Hence show that
Now here I have to get a reduction formula for . Also I have to prove that
Therefore I’ll start with the integration of .
As I can see from the example itself, I’ll write as
Also, from the standard formulas in trigonometry, I know that
Therefore I can say that
So the reduction formula for will be
Then I’ll simplify it as
And that gives
Now I’ll integrate . Thus it will be
And that means
where is the integration constant. So this gives
Therefore will be
If I say, , then it will be
Also, if , then
And this is the answer to the first part of this example.
Next, I’ll show that .
Thus I’ll substitute the limits in equation (1). So it will be
Also, I already know that
So will be
Then I’ll simplify it to get
Therefore I have also proved the relation in the second part as well.
Hence I can conclude that these are the solutions to the given example.
