Answer:
0.5,1.2,23,-34,-73
Step-by-step explanation:
The answer is 4, because of you count the number of Doty’s on the 6 and up, you would count 4 dots!
Step-by-step explanation:
L.H.S=(1-cosB)(1+cosB)
=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}
=sin^2B
=1/cosec^2B
Therefore,L.H.S=R.H.S proved
