Area bounded by curve `y=sinx`, whit x-axis, when x varies from 0 to `(pi)/(2)` is :-

A

1 unit

B

2 units

C

3 units

D

0

Text Solution

Verified by Experts

The correct Answer is:
A

area under of curve `int_(0)^(pi//2) ydx`
`=int _(0)^(pi//2) sin xdx`
`= - cos x |_(0)^(pi//2)`
`=-[ cos ""(pi)/(2) -cos 0^(@)]=1`
