Question : If $\sin \theta-\cos \theta=\frac{1}{5}$, then find the value of $\sin \theta+\cos \theta$.
Option 1: $\frac{5}{7}$
Option 2: $\frac{7}{5}$
Option 3: $\frac{5}{3}$
Option 4: $\frac{3}{5}$
Correct Answer: $\frac{7}{5}$
Solution : Given, $\sin \theta-\cos \theta=\frac{1}{5}$ Squaring both sides, we get, $\sin^2 \theta+\cos^2 \theta -2\sin \theta \cos \theta=\frac{1}{25}$ $⇒1-2\sin \theta \cos \theta=\frac{1}{25}$ $⇒2\sin \theta \cos \theta=\frac{24}{25}$ Adding 1 with both sides, we get, $⇒\sin^2 \theta+\cos^2 \theta +2\sin \theta \cos \theta=1+\frac{24}{25}$ [$\because \sin^2 \theta+\cos^2 \theta=1$] $⇒(\sin \theta+\cos \theta)^2=\frac{49}{25}$
