If `cos theta = 3/5` and `theta` lies in the fourth quadrant, find the value of `cosec theta + cot theta.`

If tan theta = - 3//5 and theta is not in the second quadrant, find the values of sec theta and cosec theta.

If sin theta = - (3)/(5) and theta lies in the third quadrant, then the value of cos (theta//2) is

If sin theta+cos theta=0 and theta lies in the fourth quadrant,find sin theta and cos theta

If tan theta = -1/sqrt(5) and theta lies in the fourth quadrant, then: cos theta =

If cos theta. cosec theta=-1 and theta lies in fourth quadrant then find cos theta and cosec theta

(i) If sin the sec theta sec theta =-1 and theta lies in the second quadrant find "sin" theta and sec theta (ii) If cos theta cosec theta =- 1 and theta lies in the in the fourth quadrient find cos theta and cosectheta

If costheta=3//7,and theta lies in the fourth quadrant, evaluate : sin(theta//2),cos(theta//2),tan(theta//2).
