Question

If $a=\cot 2^0,b=\cot 2$, then which of the following statement(s) is/are true ?

• A. $a=b$
• B. $a>b$
• C. $a<b$
• D. $a=2b$

Answer 1

The correct option is B $a>b$

$1rad\approx {57.29}^{o}2rad\approx {114.59}^o$

$a=\cot 2^{\circ }⟹a>0(2^{\circ }\in Istquadrant)$

$b=\cot 2⟹b<0(2\in IIndquadrant)$

$⟹a>b$
