Question : If $4 \sin ^2 \mathrm{A}-3=0$ and $0 \leq \mathrm{A} \leq 90^{\circ}$, then $3 \sin \mathrm{A}-4 \sin ^3 \mathrm{A}$ is:
Option 1: $\frac{1}{2}$
Option 2: $\sqrt{\frac{3}{2}}$
Option 3: $0$
Option 4: $1$
Correct Answer: $0$
Solution : $4 \sin ^2 \mathrm{A}-3=0$ $⇒\sin ^2 A = \frac{3}{4}$ $⇒\sin A = \frac{\sqrt{3}}{2}$ $3 \sin \mathrm{A}-4 \sin ^3 \mathrm{A}$ $=3 (\frac{\sqrt{3}}{2}) - 4 (\frac{\sqrt{3}}{2})^3 $ $=3 (\frac{\sqrt{3}}{2}) - 4 (\frac{\sqrt{3}}{2})^3 $ $=3 (\frac{\sqrt{3}}{2}) - 4 (\frac{3\sqrt{3}}{8}) $ $=(\frac{3\sqrt{3}}{2}) - (\frac{3\sqrt{3}}{2}) $ $= 0$ Hence, the

Question : Find the value of $\frac{\cos A}{1+\sin A}+\frac{1+\sin A}{\cos A}+2$.
Option 1: $1+2 \sec A$
Option 2: $2-\sec A$
Option 3: $2+\sec A$
Option 4: $2(1+\sec A)$
Correct Answer: $2(1+\sec A)$
Solution : Given: $\frac{\cos A}{1+\sin A}+\frac{1+\sin A}{\cos A}+2$ = $\frac{\cos^2A+1+\sin A+\sin A+\sin^2A}{(1+\sin A)(\cos A)}+2$ = $\frac{2+2\sin A}{(1+\sin A)(\cos A)}+2$ = $\frac{2(1+\sin A)}{(1+\sin A)(\cos A)}+2$ = $\frac{2}{\cos A}+2$ = $2\sec A+2$ = $2(1+\sec A)$ Hence, the correct answer is $2(1+\sec A)$.
Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error".
