यदि `theta` न्यूनकोण हो तो देखिये की `tan theta gt sin theta` |
|
Answer» माना की ABC एक समकोण त्रिभुज है जिसमे `angle B=90^(@)` तथा `angle A= theta, AB=x BC=y, AC=r` `therefore sin theta =(y)/(r )` और `cos theta =(x)/(r )` अब `sin theta + cos theta =(y)/(r )+(x)/(r )=(y+x)/(r ) gt1` `tan theta =(y)/(x)` और `sin theta =(y)/(r )` `therefore x lt r therefore (y)/(r ) gt (y)/(r ) rarr tan theta gt sin theta` |
