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
The answer is 1. That was easy because any number to the power of 0 is just 1.
<span>this polynomial has a repeated factor in (x - 2). so its true</span>
59.6 is the answer rounded to the nearest tenth
