Question

The value of the integral is?

Answer 1

dot dot dot....

Answer 2

\[\Huge \int\limits_{-\frac{\pi}{2}}^{\frac{\pi}{2}} \frac{\sin^2x}{1+2^x}dx\]

Answer 3

I think it's 0.4317

Answer 4

nope

Answer 5

@hartnn

Answer 6

king's rule is goona work here

Answer 7

do you what is that?

Answer 8

:O no

Answer 9

replaze x by (upper limit+lower limit -x) and those two limits will be equal....name them both S.....then add both equations

Answer 10

oh i know that,didnt knew the name or such

Answer 11

so tried that?

Answer 12

it will give me the question itself

Answer 13

okay no

Answer 14

\[\Huge \int\limits_{-\frac{\pi}{2}}^{\frac{\pi}{2}}2^x \frac{\sin^2x}{1+2^x}dx\]

Answer 15

2^x +1 will cancel out

Answer 16

add both the integrals

Answer 17

\[\Huge 2I=\int\limits_{\frac{-\pi}{2}}^{\frac{\pi}{2}}\sin^2xdx\]

Answer 18

Thank you :)

Answer 19

no prob... (:
