Question

Determine the area bounded by the curve=cos x, the x-axis, and the vertical x=π and x=3π/2.

Answer 1

Do you have any ideas how to start?

Answer 2

Remember that the Definite integral from a to b of a function, represents the area under that function.

Answer 3

\[\int\limits_a^b f(x) dx = Area\]

Answer 4

I think it's \[\int\limits_{\pi /4}^{3\pi/2}\cos x dx\]. Is it correct?

Answer 5

It's almost correct. The lower limit is not pi/4

Answer 6

It is just pi

Answer 7

Oh yeah! Thank you very much!

Answer 8

U r welcome
