Solution and Explanation
Trigonometry is that branch of mathematics which deals with the relationship between the angles and sides of triangles. Inverse trigonometric function plays an important role in calculus and integrals.
Like: For Sine function: R—-->[-1,1],
For Cosec function : R—-->-(-1,1),
Therefore, \(sec^{-1}(1)= 0\)
