Question : If $\sin \theta+\cos \theta=\frac{\sqrt{11}}{3}$, then what is $\sin \theta-\cos \theta$?
Option 1: $\frac{\sqrt{7}}{4}$
Option 2: $\frac{\sqrt{7}}{3}$
Option 3: $\frac{\sqrt{5}}{3}$
Option 4: $\frac{\sqrt{5}}{2}$
Correct Answer: $\frac{\sqrt{7}}{3}$
Solution : Given: $\sin \theta+\cos \theta=\frac{\sqrt{11}}{3}$ (equation 1) Squaring both sides of the equation 1, we get, $(\sin \theta+\cos \theta)^2=(\frac{\sqrt{11}}{3})^2$ ⇒ $\sin^2 \theta+\cos^2 \theta+2\sin \theta \cos \theta=\frac{11}{9}$ ⇒ $1+2\sin \theta \cos \theta=\frac{11}{9}$ ⇒ $2\sin \theta \cos \theta=\frac{11}{9}-1$ ⇒ $2\sin \theta \cos \theta=\frac{2}{9}$ (equation 2) Substitute the value
