Solve the equation `cot((theta )/(2))-"cosec"((theta)/2)=cot theta `

(b) cosec theta=1+cot theta

(b) cosec theta=1+cot theta

Prove that cot(theta/2)-tan(theta/2)=2cot theta

Number of solutions of the equation cot( theta ) + cot( theta +(pi)/(3))+ cos ( theta -(pi)/(3))+ cot( 3 theta ) =0 , where theta in ( 0,(pi)/(2))

Prove that sin(2theta)/(1-cos2theta)=cot theta

Solve the equations : cot^2theta+3/(sin theta)+3=0

Solve: cot5theta=cot2theta

Solve the equation 2 tan theta - cot theta + 1 = 0

The general solution of the equation, 2cot.(theta)/(2)=(1+cot theta)^(2) is (n in Z)

prove that (cosec theta + cot theta)/(cosec theta- cot theta) = (cosec theta +cot theta)^2
