Graph of trigonometric functions2

The domain of trigonometric functions can be restricted to any one of their branch (not necessary principal value) in order to obtain their inverse function s.

Find the value of the trigonometric functions : sin 1830^@

Find the values of the trigonometric function sin 765^(@)

Find the value of the trigonometric functions: cot\ (13pi)/3

Find the values of the trigonometric function sin (-(11pi)/3)

Find the values of the trigonometric function sin( -11pi/3)

Find the values of the other five trigonometric functions in each of the following: costheta=-1/2,theta in quadrant II

Find the value of the other five trigonometric functions : cot theta = -12/5 , pi/2 lt theta lt pi

Find the value of the other five trigonometric functions : sec theta = 13/5 , (3pi)/2 lt theta lt 2pi

If costheta=-3/5 and pilttheta<(3pi)/2 find the values of other five trigonometric functions and hence evaluate (cosectheta-cottheta)/(sectheta-tantheta) .
