Question

Integrate 1/(1+x2) for limit [0,1].

​

Answer 1

Step-by-step explanation:

answer is 45° or π/4

because it's a simple formula

Answer 2

Step-by-step explanation:

let it given that

1/(1+x^2) limit for [0,1]

then

the integral of 1/(1+x^2) is

tan inverse x

[ 1/( a^2+ x^2) is 1/ a tan inverse

x/ a]

so now put the limit

tan inverse (1) - tan inverse (0)

the answer is

pi/4
