Solve `(costheta)/(1+sintheta)+tantheta=2`

costheta(tantheta+2)(2tantheta+1)=?

Prove that : (1+sintheta)/(costheta)+(costheta)/(1+sintheta)=2sectheta

Solve: costheta+sintheta=cost2theta+sin2theta

If tantheta=(a)/(b) ,then find the value of (costheta+sintheta)/(costheta-sintheta) .

If tantheta =p/q , then the value of (p sintheta-q costheta)/(p sintheta+q costheta) is

Prove that : (1-costheta)/(sintheta)+(sintheta)/(1-costheta)=2"cosec "theta

(sintheta)/(1+costheta) + (1+costheta)/(sintheta) = 2 cosec theta

Prove that : (sintheta)/(sectheta+tantheta-1)+(costheta)/("cosec"theta+cottheta-1)=1

If 0^(@)lethetale90^(@) , then solve the following equations : (i) (costheta)/(1-sintheta)+(costheta)/(1+sintheta)=4 (ii) (cos^(2)theta-3costheta+2)/(sin^(2)theta)=1 (iii) (costheta)/("cosec"theta+1)+(costheta)/("cosec"theta-1)=2
