1Wait I'll be posting the answer........
find the range of the function not using differentiation (i.e maxima and minima not allowed ) :-
f(x) = (sin2x + sinx - 1) / (sin2x - sinx +2 )

19what are u asking ,dear? we are to use differentiation but not maxima,minima....what is this???please clarify !!!
24Write f(x) as
f(x)=\frac {\sin ^2x +\sin x -1}{\sin ^2 x- \sin x +2}=\frac {\sin ^2x -\sin x +2-3+2\sin x}{\sin ^2 x- \sin x +2}=1+\frac {2\sin x -3}{\sin ^2 x-\sin x +2}
isnt it better now ?
1sorry it is "tell me if something is wrong" in above post..............
24dont u think u have made this ques too tuff ??
or have I made some mistake ...[3][3]
1I think so. My answer looks quite lengthy and somewhat complex.
I'll be really glad if someone posts solution which is not as complex as this.......
