Question

integrate (1+ cosx)1/2

Answer 1

\[\sqrt{1+ \cos x}\] do you mean this?

Answer 2

why we root the equation

Answer 3

does the question look like this \[\sqrt{1+ \cos x}\] or is it just that (1+ cos x) is multiplied by half?

Answer 4

it is (1+ cos x) is multiplied by half

Answer 5

x/2 +sinx/2

Answer 6

then ishaan is correct

Answer 7

but how i need to know i cant understand

Answer 8

is it
\[\int \frac{1+\cos(x)}{2}dx\] or
\[\int (1+\cos(x))^{\frac{1}{2}}dx\] b money is on the second one

Answer 9

1/2 + cos x/2 dx
integrating the first expression simply gives x/2 and the second sinx/2
there is no complicated algebra...just the basic formulas to integrate are used.
check the list of formulas in your book for cos x, you will find that its sin x.

Answer 10

and integration of dx is simply x.

Answer 11

my money is still on the second one

Answer 12

especially in light of next question.

Answer 13

she confirmed its the first one. she might have deleted that post.
