cosec^(2)theta-cot^(2)theta

cosec^(4)theta+cot^(2)theta+cosec^(2)theta)"=

cosec^(6)theta-cot^(6)theta-3cot^(2)theta.cosec^(2)theta=?

csc^(6)theta-cot^(6)theta=1+3csc^(2)theta cot^(2)theta

cosec^(2)theta=1+cot^(2)theta

f(theta)=sin^(2)theta+cos^(2)theta+tan^(2)theta+sec^(2)theta+csc^(2)theta+cot^(2)theta then the minimum value of f(theta) is

For 0 prec theta prec 90 , if 2 cos^2 theta=3 sin theta , then the value of (cosec^2 theta-cot^2 theta+cos^2 theta) is equal to : 0 prec theta prec 90 के लिए , यदि 2 cos^2 theta=3 sin theta है, तो (cosec^2 theta-cot^2 theta+cos^2 theta) किसके बराबर होगा?

Without expanding show that: cosec theta,cot^(2)theta,1cot^(2)theta,csc^(2)theta,-142,40,2]|=0

cosec^4 theta-cot^4 theta=cosec^2theta+cot^2 theta

what is value of: |[cosec^2theta,cot^2theta,1],[cot^2theta,cosec^2theta,-1],[42,40,2]| ?
