To determine the domain and range of y =
(sinx)^2.
The domain is the set of all real values of x for
which the image or range or y values are real.
In (sinx)^2
, the variable x can can take any real value . So the domain is : - infinity <
x < infinity.
The for any x, |sinx | < =
1.
Therefore forany x , 0 = < (sinx)^2 < =
1.
Therefore the range of the function is : 0 =< y
< =1.
