Mark the tick against the correct answer in the following:
The value of is
To Find: The value of
Now, let x =
cot x =cot (
)
Here range of principle value of cot is []
x =
[
]
Hence for all values of x in range [] ,the value of
is
cot x =cot (
) (
cot (
)= cot (
) )
cot x =cot (
) (
cot (
)= cot
)
x =
