Answer:
The exact value of cotФ is
Step-by-step explanation:
Given as:
The value of cosec Ф =
Let the value of cotФ = x
Now, According to question
∵ sinФ = .....1
Put the value of cosec Ф = in eq 1
i.e sinФ =
Or, sinФ =
<u>Again</u>
∵ cosФ =
So, cosФ =
Or, cosФ =
Or, cosФ =
∴ cosФ =
<u>Again</u>
we know that cotФ =
So, cotФ =
Or, cotФ =
As according to question sinФ lies in third quadrant
So, cotФ =
Hence, The exact value of cotФ is . Answer
