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: $\frac{\sqrt{5}}{2}$

Team Careers360 22nd Jan, 2024

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
