Question : If $\sec A - \tan A = p$, then find the value of $\sec A$.

Option 1: $\frac{p^2-1}{p^2+1}$

Option 2: $\frac{\mathrm{p}^2+1}{\mathrm{p}^2-1}$

Option 3: $\frac{\mathrm{p}^2+1}{\mathrm{p}}$

Option 4: $\frac{\mathrm{p}^2+1}{2 \mathrm{p}}$

Team Careers360 24th Jan, 2024

Correct Answer: $\frac{\mathrm{p}^2+1}{2 \mathrm{p}}$


Solution : $\sec A - \tan A = p$
$\frac{1}{\cos A} - \frac{\sin A}{\cos A} = p$
$\frac{(1-\sin A)^2}{(\cos A)^2} = p^2$
$\frac{(1-\sin A)^2}{1-\sin^2 A} = p^2$
$\frac{(1-\sin A)^2}{(1-\sin A)(1+\sin A)} = p^2$
$\frac{1-\sin A}{1+\sin A}= p^2$
$1-\sin A = p^2 + p^2\sin A$
$\sin A
