Tan x + tan 2x = 0
Is that way is right or wrong for find general solution in trigonometry?
tan x + tan 2x = 0
tan x = - tan 2x
tan x= tan (π - 2x)
x=nπ/3 + π/3

stated method in question is wrong!

Step-by-step explanation:

We need to find the general solution of x ! for the equation

⇒  

⇒  

⇒  

Now , we know that

⇒  

⇒  

Now , we know that

⇒  

⇒  

⇒  

⇒       ......(1)

General solution of Tan x is : , \

Here , from equation (1) we get   . Hence general solution is :

⇒ .Therefore , stated method in question is wrong!

a) 7x=7
