Vedclass · Answer

(A) Given $P = \frac{1}{2} \sin^2 	heta + \frac{1}{3} \cos^2 	heta$. Using the identity $\cos^2 	heta = 1 - \sin^2 	heta$,we get: $P = \frac{1}{2} \sin^2 	heta + \frac{1}{3} (1 - \sin^2 	heta)$ $P = \frac{1}{3} + (\frac{1}{2} - \frac{1}{3}) \sin^2 	heta$ $P = \frac{1}{3} + \frac{1}{6} \sin^2 	heta$. Since $0 \leq \sin^2 	heta \leq 1$,we have: $0 \leq \frac{1}{6} \sin^2 	heta \leq \frac{1}{6}$ Adding $\frac{1}{3}$ to all parts: $\frac{1}{3} \leq \frac{1}{3} + \frac{1}{6} \sin^2 	heta \leq \frac{1}{3} + \frac{1}{6}$ $\frac{1}{3} \leq P \leq \frac{1}{2}$.

If $P = \frac{1}{2} \sin^2 \theta + \frac{1}{3} \cos^2 \theta$,then:
