Question

Distance of the points $(\cot a,1)$ from origin is

• A. $|\sec a|$
• B. $|\cot a|$
• C. $|Co\sec a|$
• D. $|\tan a|$

Answer 1

The correct option is C $|Co\sec a|$

Distance b/w 2 points

$A=(cota,1),B=(0,0)$

$AB=\sqrt{(cota-0{)}^2+(1-0{)}^2}$

$\Rightarrow \sqrt{co{t}^{2}a+1}\Rightarrow \sqrt{cose{c}^{2}a}$

$=\left|coseca\right|$

option C is correct.
