Medal! Calculus! Question Below

Answer 1

It gives you a hint to use \( \int \frac{1}{1+x^2} =\arctan(x) \).

Then you can evaluate the result. \( \arctan(x) \bigg|_{-1}^{1} = \arctan(1) - \arctan(-1) \).

Since \( \arctan(1)=\frac{\pi}{4}\), you get \( \frac{\pi}{4}\ - (-\frac{\pi}{4}\) \)

Answer 2

so the answer is pi/2? @DoughnutTable

Answer 3

well first we use the power of love the mathematically solve

Answer 4

and then you will find the answer deep within your heart

Answer 5

got that? write that down
