Tan x + tan 2x = 0

choli [55]

stated method in question is wrong!

Step-by-step explanation:

We need to find the general solution of x ! for the equation $tan x + tan 2x = 0$

⇒ $tan x + tan 2x = 0$

⇒ $(tan x + tan 2x)-tan2x = 0-tan2x$

⇒ $tan x = -tan2x$

Now , we know that $tan(\pi -2x) = -tan2x$

⇒ $tan x = -tan2x$

⇒ $tan x = tan(\pi -2x)$

Now , we know that $TanA = TanB \\A=B$

⇒ $tan x = tan(\pi -2x)$

⇒ $x = \pi -2x$

⇒ $3x = \pi$

⇒ $x = \frac{\pi}{3}$ ......(1)

General solution of Tan x is : $x = n\pi + \alpha$ , \

Here , from equation (1) we get $\alpha =\frac{\pi }{3}$ . Hence general solution is :

⇒ $x = n\pi +\frac{\pi }{3}$ .Therefore , stated method in question is wrong!

Answers for the 2 boxes please :)

Answer:

Step-by-step explanation:

2x - 2y = 2

5x + 2y = 12

7x = 14

(2x - 2y = 2)-5

(5x + 2y = 12)2

-10x + 10y = -10

10x + 4y = 24

14y = 14

x = 2

y = 1

(2,1)
