যদি sin-1 x + sin-1 y = \(\rm \frac{3\pi}{4}\) , তাহলে cos-1 x + cos-1 y = ? .
Answer (Detailed Solution Below)
Elementary Properties and Identities Question 1 Detailed Solution
অনুসৃত ধারণা:
sin-1 x + cos-1 x = \(\rm \frac{π}{2}\)
গণনা:
sin-1 x + sin-1 y = \(\rm \frac{3π}{4}\)
⇒ \(\rm \left ( \frac{π}{2} -cos^{-1}x\right ) + \left ( \frac{π}{2}- cos^{-1}y\right ) = \frac{3π}{4}\)
⇒ π - ( cos-1 x + cos-1 y ) = \(\rm \frac{3π}{4}\)
⇒ cos-1 x + cos-1 y = \(\rm\frac{\pi}{4}\)
