"যদি `sintheta=1/3` হয়, তাহলে `2cot^2theta+2` এর মান বের করুন।"

cosec^2 theta - cot^2 theta = 1 +…..

(1 - cos^(2)theta)cot^(2)theta

If cos^2theta-sintheta=1/4 then sintheta=?

(sintheta+sin2theta)/(1+costheta+cos2theta) =

Prove that: ("cosec" theta + cot theta)/("cosec" theta - cot theta) = ("cosec" theta + cot theta )^(2) = 1 + 2 cot^(2) theta + 2 "cosec" theta cot theta .

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

(cot2 theta-cot3 theta)/(cot theta) is equal to

(sintheta+sin2theta)/(1+costheta+cos2theta)=?

2sin^(2)theta-3sintheta=-1 :find theta

If sin theta_1 + sin theta_2 + sintheta_3 =3 then cos theta_1 + cos theta_2 + costheta_3 is equal to
