Ex 8.3, 3 Choose the correct option. Justify your choice. (iii) (sec A + tan A) (1 β sin A) sec A (B) sin A (C) cosec A (D) cos A (sec A + tan A) (1 β sin A) = (π/(πππ π¨)+πππβ‘π¨/πππβ‘γ π¨γ ) (1 βsinβ‘γ π΄)γ = ((1 + sinβ‘γ π΄)γ)/cosβ‘γ π΄γ Γ(1 βsinβ‘γ π΄)γ = ((1 + sinβ‘γ π΄)(1 βγ sinγβ‘γ π΄)γ γ)/cosβ‘γ π΄γ = ((1^2 βγ sin2γβ‘γ π΄)γ)/cosβ‘γ π΄γ = ((π βγ π¬π’π§πγβ‘γ π¨)γ)/cosβ‘γ π΄γ = (ππππ π¨)/cosβ‘γ π΄γ = cos A So, the correct answer is (d)
