1.

4. (tan theta+ 2) (2 tan theta + 1) = 5 tan A + sec2 thetha. state true of false​

Answer»

ANSWER:

it is wrong

Step-by-step explanation:

Given EQUATION is :

= > (TAN theta + 2)(2 tan theta + 1)

= > (2tan^2 theta + tantheta + 4tantheta + 2)

= > (2(sec^2theta - 1) + 5tantheta + 2)

= > (2sec^2 theta - 2 + 5tantheta + 2)

= > (2sec^2theta + 5tantheta).

Therefore the final answer will be 2sec^2theta + 5tantheta.
