Suppose the point with coordinates (-12 ...

Suppose the point with coordinates `(-12 ,5)` is on the terminal side of angle `theta` . Find the values of the six trigonometric functions of `thetadot`

Text Solution

Verified by Experts

Since terminal ray lies in the second quadrant, we have
`{:(,sintheta=5/13,cosectheta=13/5),(,costheta=-12/13,sectheta=-13/12),(,tantheta=-5/12,cottheta=-12/5):}`
