what did i do wrong (1 Viewer)

[anonymoushehe]

I know i did a longer way, but I was wondering why my answer is wrong because I tried to find the matching area for normal cos curve and integrated from there?

u could just use integration by parts

in the original cos inverse curve the integral would be equivalent to the area under the curve as cos inverse is always positive (A1 + A2)
so the integral that you perform should have the area that you shaded and not the definite integral (so when you evaluate A2 it should be π - 1 instead - so A1 + A2 = 1 + (π - 1) )
sorry if that's confusing idk how to word it
