Prove that (sinA+cosecA)^2 + (cosA+secA)^2 = 7 + tan^2A+cot^2A | Trigonometry Questions

Показать описание

Another very good and interesting question of trigonometry for class 10, 11, 12 students. The question is super easy to solve, just looks very complicated :)

This question is also listed as one of the following ways at many places:

(sinA+cosecA)^2 + (cosA+secA)^2 = 7 + tan^2A+cot^2A,
(sin x + cosec x)^2 + (cos x + sec x)^2 = 7 + tan^2x+cot^x,
(sinθ+cosecθ)^2 + (cosθ+secθ)^2 = 7 + tan^2θ+cot^2θ,

(sinθ+cosecθ)² + (cosθ+secθ)² = 7 + tan²θ+cot²θ,
(sin A + cosec A)² + (cos A + sec A)² = 7 + tan² A + cot² A,
(sin x+cosec x)² + (cos x+sec x)² = 7 + tan²x+cot²x,
