Think about for .

The smaller gets, the bigger gets, and the bigger gets, the smaller gets.


So where is at its minimum? This is where will be at its maximum.

Similarly, where is at its maximum? This is where will be at its minimum.

We Will Do This :



To Find Minimum -> Sinx=1 ( The Maximum of Sinx) So We Have :



To Find The Maximum - > Sinx=-1 { The Min of Sinx) So We Have:




So
