Question

What is the integral of (cos(x)/x)^2 + (sin(x)/x)^2

Answer 1

recall the pythagorean identity
\(\Large \sin^2 x+\cos^2 x =1\)

does that help you in simplifying your function ?

Answer 2

So ultimately I am taking the interval of y^-1

Answer 3

x^-1 sorry

Answer 4

x^-2 you mean ?

Answer 5

never mind it makes sense thank you so much so the answer would be x^-1

Answer 6

-x^-1**

Answer 7

yes!
good work :)
