\(\rm \frac{sin\space23°}{cos\space67°}+\frac{cos\space71°}{sin\space19°}\)
பயன்படுத்தப்படும் சூத்திரம்:
sin (90°- x) = cos x
cos (90°- x) = sin x
கணக்கீடு:
\(\rm \frac{sin\space23°}{cos\space67°}+\frac{cos\space71°}{sin\space19°}\)
⇒ sin(90° - 67°)/cos 67° + cos (90° - 19°)/sin 19°
⇒ cos 67°/ cos 67° + sin 19°/sin 19°
⇒ 1 + 1 = 2
∴ தேவையான முடிவு = 2
