Text Solution

Solution : We can draw the point (-12,5) at the XY-axis.<br> Please refer to see the graph.<br> It will become a right angle triangle with base = 12 and perpendicular = 5.<br> :. Hypotenuse = 12^2+5^2 = 13<br> As it is in second quadrant, only sin theta and cosec theta will be positive.<br> :.sin theta = 5/13<br> cos theta = -12/13<br> tan theta = -5/12<br> cot theta = -12/5<br> cosec theta = 13/5<br> sec theta = -13/12<br>
