sec2 A + (cosec2 A - 1) - (1 + tan2 A) - cot2 A = __
ব্যবহৃত ধারণা:
পিথাগোরাসের ত্রিকোণমিতিক অভেদ:
cosec2 θ - 1 = cot2 θ
1 + tan2 θ = sec2 θ
গণনা:
⇒ sec2 A + (cosec2 A - 1) - (1 + tan2 A) - cot2 A
ত্রিকোণমিতিক অভেদের মান বসিয়ে,
⇒ sec2 A + cot2 A - sec2 A - cot2 A = 0
অতএব, sec2 A + cot2 A - sec2 A - cot2 A এর মান 0।
সুতরাং, সঠিক উত্তর হল বিকল্প (2)
