Detailed Solution
Download Solution PDFप्रयुक्त अवधारणा:
sin3θ = 3sinθ - 4sin3θ?
गणना:
sin 10°- \(\dfrac{4}{3}\) sin3 10°
⇒ \(\dfrac{\text{3 Sin10 - 4Sin}^310}{3}\)
⇒ \(\dfrac{\text{Sin3(10)}}{3}\)
⇒ \(\dfrac{\text{Sin30}}{3}\) = \(\dfrac{1}{2}\) × \(\dfrac{1}{3}\) = \(\dfrac{1}{6}\)
sin 10°- 4/3 sin3 10°= \(\dfrac{1}{6}\)
