If `cosectheta+cottheta=5`,then evaluate `sectheta`.

If cosectheta+cottheta=5/2 ,then the value of tantheta is………..

If cosec theta - cottheta = (1)/(3) , then cosec theta + cot theta =

Evaluate: 5!

If cosectheta-cottheta=2017 , then quadrant in which theta lies is......... (A) I (B) IV (C) III (D) II

Prove the following: (frac(1+cottheta+cosectheta)(1-cottheta-cosectheta))=(frac(cosectheta+cottheta-1)(cottheta-cosectheta+1))

Prove the following: (frac(cosectheta+cottheta+1)(cottheta+cosectheta-1))=(frac(cottheta)(cosectheta-1))

(6) If cosectheta = 61/60, sectheta = 61/11, then cot theta =……..

(8) If tan theta =1, then sectheta =…….

Prove the following: (frac(cosectheta+cottheta-1)(cosectheta+cottheta+1))=(frac(1-sintheta)(costheta))

If cottheta+tantheta=2cosectheta , the general value of theta is
