How we should find the trigonometric ratioes of 90degaree and 0degaree |
| Answer» let B=base L=altitude and H=hypotenuseAt 900 B =0 and L=H,so sin 90=L/H=1 and cos90=0/H=0 tan 90 = L/B = L/0= infiniteAt 00 L=0 and B=L so sin 0=0 , cos 0 =b/h=1 tan 0=L/B=0/b=0Value of cot,sec and cosec can be found accordingly\xa0 | |
