Mark the tick against the correct answer in the following:
The principal value of is
To Find:The Principle value of
Let the principle value be given by x
Now, let x =
cos x=
cos x=cos() ()
x =
The principal value of cosec-1(2) is
The principal value of cot-1 (-1) is
The value of is
The value of
If x ≠ 0 then cos (tan-1 x + cot-1 x) = ?
If then sin x = ?
If then x = ?
If then
(tan-1 2 + tan-1 3) = ?
If tan-1 x + tan-1 3 = tan-1 8 then x = ?
Range of sin-1 x is
Range of cos-1 x is
Range of tan-1 x is
Range of sec-1 x is
Range of coses-1 x is
Domain of cos-1 x is
Domain of sec-1 x is
