Q (7) Find the values of the trigonometric functions

\small cosec \ (-1410\degree)

Answers (1)

We know that value of cosec x repeats after an interval of 2\pi \ or \ 360\degree
cosec (-1410\degree) = cosec (-1410\degree + 360\degree\times4)\\ cosec\ 30\degree = 2

or

cosec(-1410\degree)= - cosec(1410\degree)\\= -cosec(4 \times 360\degree - 30\degree)= - cosec(-30\degree) = 2
