Solve the following equations : i) tantheta=cottheta , ii) cos2theta=2sin^(2)theta iii) tan3theta=-sqrt(3) , iv) sin2theta-costheta=0 v) sec^(2)2theta=1-tan2theta

sec^(2)theta=1-tan2 theta

Find the general solutions of the following equations: sec^2(2theta) = 1-tan2theta

Show that (1)/(3) lt (sec^(2) theta - tan theta)/( sec^(2) theta+ tan theta) lt3 .

Show that: (sec^(2)theta-tan theta)/(sec^(2)theta+tan theta) lies between 3 and (1)/(3)

Prove that (sec^(2)theta-tan theta)/(sec^(2)theta+tan theta) lies between 3 and (1)/(3).

Show that (sec^(2)theta-tan theta)/(sec^(2)theta+tan theta) lies between (1)/(3) and 3.

(2sin theta tan theta(1-tan theta)+2sin theta sec^(2)theta)/((1+tan theta)^(2))=(2sin theta)/(1+tan theta)

(2sin theta*tan theta(1-tan theta)+2sin theta*sec^(2)theta)/((1+tan theta)^(2))=(2sin theta)/(1+tan theta)
