Introduction to trigonometry:Introduction to trigonometry CHAPTER – 8 EXERCISE – 8.4


QUESTION 5:-(vi) 1 + sin A = sec A + tan A 1 – sin A:QUESTION 5:- (vi) 1 + sin A = sec A + tan A 1 – sin A


sin θ – 2 sin3 θ = tan θ2 cos3 θ – cos θ:sin θ – 2 sin3 θ = tan θ 2 cos3 θ – cos θ


(viii) (sin A + cosec A)2 + (cos A + sec A)2 = 7 + tan2A + cot2A:(viii) (sin A + cosec A)2 + (cos A + sec A)2 = 7 + tan2A + cot2A Please Visit Again.
