Question : If $\sin t+\cos t=\frac{4}{5}$, then find $\sin t.\cos t$.
Option 1: $\frac{9}{50}$
Option 2: $-\frac{9}{50}$
Option 3: $\frac{9}{25}$
Option 4: $-\frac{9}{25}$
Correct Answer: $-\frac{9}{50}$
Solution : Given: $\sin t+\cos t=\frac{4}{5}$ Squaring both sides, we have, ⇒ $(\sin t+\cos t)^{2}=(\frac{4}{5})^{2}$ ⇒ $\sin^{2} t+\cos^{2} t+2\sin t.\cos t=\frac{16}{25}$ We know that $\sin^{2} t+\cos^{2}=1$ ⇒ $1+2\sin t.\cos t=\frac{16}{25}$ ⇒ $2\sin t.\cos t=\frac{16}{25}–1$ ⇒ $2\sin t.\cos t=-\frac{9}{25}$ ⇒ $\sin t.\cos t=-\frac{9}{50}$ Hence, the correct answer is
