Question
State whether the following are true or false. Justify your answer.
cot A is not defined for A = 0°.
Options
True
False
Solution
This statement is False.
Explanation:
cot A is not defined for A = 0°
As,
cot A = `cos A/sin A`
cot 0° = `(cos 0°)/(sin 0°)`
= `1/0`
= 0°
Hence, the given statement is true.
