Question

Show that 2tanx = cotx

Answer 1

Answer:

Prove that 2 tanx - cot x = - 1

proof,

2tan x - cot x + 1 = 0

2tan x - 1/tan x + 1 = 0

2tan2x - 1 + tan x = 0

2tan2x + tan x - 1 = 0

2tan2x + 2tan x - tan x - 1 = 02tan x(tan x + 1) - 1 (tan x + 1) = 0

(tan x + 1)(2tan x - 1) = 0

tan x + 1 = 0 or 2tan x - 1 = 0

tan x = -1 or tan x = 1/2x = 3π/4, 7π/4 or x = 3.6052, 0.4636
