If y= sin^(2)theta + cosec^(2)theta, theta ne 0 , then

sin(pi+theta)sin(pi-theta)cosec^2theta=

The sin theta + "cosec" theta =2 , then: sin^(2)theta + "cosec"^(2)theta =

(cos^(2)theta)/(sin theta)-cosec theta+sin theta=0

If y=sin^2 theta+cosec^2 theta, theta!=0, then (A) y=0 (B) yle2 (C) yge-2 (D) yge2

If y=sin^2 theta+cosec^2 theta, theta!=0, then (A) y=0 (B) yle2 (C) yge-2 (D) yge2

If sin theta + cosec theta =2 ,then the value of sin^5theta cosec^5 theta ,when 0^@ le theta le 90^@ , is

If (1/(1+cosec theta ) - 1/(1-cosec theta ))cos theta= 2 , 0^circ lt theta lt 90^circ , then the value of sin^(2) theta + cot^(2) theta + sec^(2) theta is: यदि (1/(1+cosec theta ) - 1/(1-cosec theta ))cos theta= 2 , 0^circ lt theta lt 90^circ , है,तो sin^(2) theta + cot^(2) theta + sec^(2) theta का मान हैः
