One root of the equation tan x = x is

One root of the equation tan x = x is Correct Answer x = 0

Explanation:

Plotting tan x and x on the graph, we found tan x = x at some values.

So, from the graph, we can say x = 0 is one of the solution for tan x - x = 0

Also, numerically if we put x = 0 in tan x = x, we get

LHS = tan x = tan 0° = 0

RHS = x = 0

⇒ LHS = RHS

Hence, One root of the equation tan x = x is x = 0.
