I : If ` sec theta + tan theta = 1//5 " then " theta ` lies in ` Q_4`. II : If ` "cosec" theta - cot theta = 1/3" then " theta `lies in `Q_1` .

If sec theta - tan theta = 1/2, then theta lies in the

If sec theta + tan theta = 1.5 then theta lies in the quadrant

If " cosec " theta - cot theta =1//3 then theta lies in the quadrant

( sec theta + tan theta )/("cosec " theta + cot theta ) -(sec theta - tan theta )/( " cosec" theta - cot theta )=

If sqrt((1+ cos theta )/(1- cos theta ))="cosec " theta + cot theta " then " theta lies in the quadrants

(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 cosec theta + cot theta = q , show that cosec theta - cot theta = 1/q and hence find the values of sin theta and sec theta .

( 1 + tan theta + sec theta ) ( 1 + cot theta - cosec theta ) =

Prove that: sin theta(1+ tan theta) + cos theta (1+ cot theta) = sec theta + "cosec" theta

Prove that: sin theta (1 + tan theta) + cos theta (1+ cot theta) = sec theta + cosec theta .
