okkkkkkkkkkkkkk bye

Answer 2

Answer:

2

Step-by-step explanation:

$\int\limits^{\pi/2}_0 {(sinx+cosx)} \, dx$

$: \longmapsto \int\limits^{\pi/2}_0 {sinx} \, dx+\int\limits^{\pi/2}_0 {cosx} \, dx$

$: \longmapsto [-cosx]^{\pi/2}_0+ [sinx]^{\pi/2}_0$

$: \longmapsto [-(0-1)] + [1-0]$

$: \longmapsto 1 + 1$

$: \longmapsto \underline {\boxed {\mathbf {2}}}$

Hope it helps!!
