Question

( sin alpha=P )
( tan frac{4}{2} ) and cat ( frac{alpha}{2} ) are the rates
( =tan frac{alpha}{2} times frac{1}{tan frac{alpha}{2}}=1 )
Whad ( left.operatorname{eq}^{1}=right) )
[
x^{2}-(text { sum of } operatorname{roats}) x+text { product of reats }
]
( Rightarrow x^{2}-frac{2}{p} x+1=0 )
If ( quad 1 x^{2}-2 x+P=0 )

# Given sina = p, the quadratic equation, whose roots are (A) px2 + 2x + p = 0 (B) px2 + x + p = 0 (C) px2 - 2x + p = 0 (D) px - x + p = 0

Solution
