Question

Use part 1 of the Fundamental Theorem of Calculus to find the derivative of the function. h(x)=∫ arctan 5t dt on the interval (4, 1/x). I got -5arctan(1/x)/x^2 but it was wrong

Answer 1

any working you'll like to share?

Answer 2

I let F(x) = arctan t dt from (4,1/x). I pulled out the 5 from chain rule
