Question

If cosec 0 - sin 0 = m and sec 0 - cos 0 = n, prove that
(mm) + (mm2)% = 1​

Answer 1

Answer:

here's your answer

m2n=(cosecθ−sinθ)2(secθ−cosθ)=(sinθ1−sin2θ)2(cosθ1−cos2θ)=sin2θcosθcos4θsin2θ

⇒(m2n)=cos3θ

⇒(m2n)2/3=cos2θ

Similarly mn2=(cosecθ−sinθ)(secθ−cosθ)2=cos2θsinθsin4θcos2θ=sin3θ

⇒(m2n)2/3+(mn2)2/3=sin2θ+cos2θ=1.
