`(cottheta-costheta)/(cottheta+costheta)=(2-sqrt(3))/(2+sqrt(3))`

(sintheta+costheta)(tantheta+cottheta)=

Prove that following identities (cottheta-costheta)/(cottheta+costheta)=(cosectheta-1)/(cosectheta+1)

sqrt((cottheta+costheta)/(cottheta-costheta)) is equal to :

costheta -sintheta -cottheta +1=0

Prove that (cottheta+cosectheta-1)/(cottheta-cosectheta+1)=(1+costheta)/sintheta

Prove that (1+cosectheta-cottheta)/(1+cosectheta+cottheta)=(1-costheta)/(sintheta)

sectheta=2/sqrt(3) and cottheta=-sqrt(3)

sintheta/(1-cottheta)+costheta/(1-tantheta)=

Prove that (cosectheta+cottheta)/(cosectheta-cottheta) =((1+costheta)/sintheta)^2 .

If 4sin theta=3 ,find the value of x if sqrt((cosec^(2)theta-cot^(2)theta)/(sec^(2)theta-1))+2cottheta=(sqrt(7))/(x)+costheta
