Sinθ = 2/√5
கருத்துரு:
முக்கோணவியல் சார்பு பயன்படுத்தும் போது, sec θ and cot θ-இன் மதிப்புகளைக் கணக்கிடலாம்.
கணக்கீடு:
sin θ = (செங்குத்து)/(கர்ணம்)
∆ABC-இல்;
(AC)2 = (AB)2 + (BC)2
⇒ (√5)2 = (2)2 + (BC)2
⇒ 5 = 4 + (BC)2
⇒ (BC)2 = 5 – 4
⇒ (BC)2 = 1
⇒ BC = 1
sec θ = (கர்ணம்)/அடித்தளம்)
⇒ sec θ = √5/1 = √5
cot θ = (அடித்தளம்)/(செங்குத்து)
⇒ cot θ = 1/2
(sec θ)2 + (cot θ)2 = (√5)2 + (1/2)2
⇒ 5 + 1/4
⇒ 21/4
∴ sec2θ + cot2θ என்பதன் மதிப்பு 21/4 ஆகும்.
