Sec41=1/cos41=1/sin(90-41)
cosec41=1/sin41=1/cos(90-41)
Therefore
1/sin49*sin49+1/cos49*cos49=2
1+1=2
cosec41=1/sin41=1/cos(90-41)
Therefore
1/sin49*sin49+1/cos49*cos49=2
1+1=2
YashiDua:
I didn't get thaat how sec41=1
Cos41=1
Plz rply asap..
It is not 1 it is 1/cos41
Kk thnx dear!!
yeah

Sec41=1/cos41
=1/sin49
Cose41=1/sin41
=1/cos49
1/sin49*sin49+cos49*1/cos49
=1+1
=2
Hence, proved.
