`(tantheta+2)(2 tantheta+1) = 5 tantheta+ sec^(2)theta`

State weather each of the following statements is true or false : (tantheta+2)(2tantheta+1)=5tantheta+sec^(2)theta

Prove that : (tantheta+2)(2tantheta+1)=5tantheta+2sec^(2)theta

Prove (tantheta+2)(2tantheta+1)=5tantheta+2sec^2theta.

If tantheta=t then tan2theta+sec2theta=

tantheta + cot 2theta=2

(1-tantheta)(1+sin 2theta) = (1+tantheta)

Show that [(1, - tantheta/2),(tantheta/2, 1)][(1, tantheta/2),(-tantheta/2,1)]^-1 = [(costheta,- sin theta),(sintheta, cos theta)]

frac(sintheta [(1-tantheta) tan theta+sec^2 theta])((1-sintheta) tantheta(1+tan theta) (sec theta+tantheta)) =?

If tantheta+(1)/(tantheta)=2 then the value of tan^(2)theta+(1)/(tan^(2)theta) is equal to :

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