Question : What is the slope of the line parallel to the line passing through the points (5, – 1) and (4, – 4)?
Option 1: $– 3$
Option 2: $\frac{–1}{3}$
Option 3: $3$
Option 4: $\frac{1}{3}$
Correct Answer: $3$
Solution : Given: The points are (5, –1) and (4, –4). $\text{Slope}=\frac{y_2–y_1}{x_2–x_1}$ Substitute the given values in the above formula, we get, $\frac{–4–(–1)}{4–5}=\frac{–3}{–1}$ So, the slope of the given line is 3. The slope of the line parallel to this line is also the same. Hence, the
Question : If $\tan \frac{A}{2}=x$, then find $x$.
Option 1: $\frac{\sqrt{1+\cos A}}{\sqrt{1-\cos A}}$
Option 2: $\frac{\sqrt{1-\sin A}}{\sqrt{1+\cos A}}$
Option 3: $\frac{\sqrt{1-\cos A}}{\sqrt{1+\cos A}}$
Option 4: $\frac{\sqrt{\cos A-1}}{\sqrt{1+\cos A}}$
Correct Answer: $\frac{\sqrt{1-\cos A}}{\sqrt{1+\cos A}}$
Solution : Given: $\tan\frac{A}{2}=x$ We know, $\cos A=1-2\sin^2(\frac{A}{2})$ ⇒ $\sin(\frac{A}{2})=\sqrt{\frac{1–\cos A}{2}}$ Also, $\cos A=2\cos^2(\frac{A}{2})–1$ ⇒ $\cos(\frac{A}{2})=\sqrt{\frac{1+\cos A}{2}}$ Now, $\tan\frac{A}{2}=\frac{\sin(\frac{A}{2})}{\cos(\frac{A}{2})}$ ⇒ $x=\sqrt{\frac{1–\cos A}{2}}×\sqrt{\frac{2}{1+\cos A}}$ $\therefore x=\frac{\sqrt{1-\cos A}}{\sqrt{1+\cos A}}$ Hence, the correct answer is $\frac{\sqrt{1-\cos A}}{\sqrt{1+\cos A}}$.

Option 1: EITJUVKBP
Option 2: EJTKUVJCO
Option 3: EJTKVUJCP
Option 4: EJTKUVKCP
Correct Answer: EJTKUVKCP
Solution : Given: BUDDHISM is coded as DWFFJKUO.
Add two to the place values of the letters of the given words to get the code. BUDDHISM is coded as DWFFJKUO – B + 2 = D; U + 2 = W; D + 2 = F; D
Question : What will be the value of $\cos x \operatorname{cosec} x - \sin x \sec x$?
Option 1: $\cot \frac{2x}{2}$
Option 2: $\tan 2 x $
Option 3: $\cot 2 x $
Option 4: $ 2 \cot 2x$
Correct Answer: $ 2 \cot 2x$
Solution : Given: $\cos x \operatorname{cosec} x – \sin x \sec x$ = $\frac{\cos x}{\sin x} - \frac{\sin x}{\cos x}$ = $\frac{\cos x \cos x - \sin x \sin x}{\cos x \sin x}$ = $\frac{2(\cos^2 x - \sin^2 x)}{2\sin x \cos x}$ = $\frac{2\cos
