(v)cosec theta=-2

cottheta=-sqrt(3) and cosec theta=2

Prove that: cosec theta +cosec (theta/2)+cosec (theta/2^2)+cosec(theta/2^3)+… to n terms = cot(theta/2^n) -cot theta

Prove that: cosec theta +cosec (theta/2)+cosec (theta/2^2)+cosec(theta/2^3)+… to n terms = cot(theta/2^n) -cot theta

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

If sin theta+cosec theta=2 then sin ^(2) theta+cosec^(2) theta=

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

If cot theta= sqrt7 , then the value of (cosec^2 theta-sec^2 theta)/(cosec^2 theta+sec^2 theta) is: यदि cot theta= sqrt7 , है, तो (cosec^2 theta-sec^2 theta)/(cosec^2 theta+sec^2 theta) का मान क्या होगा ?

If Cot theta=sqrt6 , then the value of (cosec^2 theta+sec^2 theta)/(cosec^2 theta-sec^2 theta) is: यदि Cot theta=sqrt6 ,है, तो (cosec^2 theta+sec^2 theta)/(cosec^2 theta-sec^2 theta) का मान ज्ञात करें |

Prove that (tan^2 theta)/(tan^2 theta-1)+(cosec^2 theta)/ (sec^2 theta-cosec^2 theta)= -sec 2 theta .
