Question

Area of the region under
1+sinx from pi/6 to 5pi/6

Answer 1

intigrate abs(1+sin x) from pi/6 to 5 pi/6

And you might wanna check for absolute values so i made it that just in case.

Answer 2

I did this, but I get a weird answer.

Answer 3

Not the textbook one.

Answer 4

if you used calculator to evaluate make sure you in radians.

Answer 5

try it without the abs()

and I get 3.826445

Answer 6

Can you show steps?

Answer 7

well integral of 1-sin(x) is just x-cos(x)

-a+cos(a)+b-cos(b)

where a is starting value and b is final value

Answer 8

Okay I did this:

(5pi/5 - cos5pi/6) - (pi/6 - cospi/6)
What am I doing wrong?
