Calculus

How do I determine the area of a region bounded by a function and the xaxis if given y=cosx and interval is [0,ð/2]. This has to do with the Fundamental Theorem of Calculus. Thanks in advance!

FTC says that the area is the definite integral.
area = Int(cosx)[0,pi/2]
= sinx [0,pi/2]
= 1  0
= 1
