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