Question

What is this answer in degrees?
cos a tan x + 3 tanx = 0

Answer 1

`x = 0, \pi`

Explanation:

Question:

`cosatanx+3tanx = 0`

Factor tanx:

`tanx(cosa+3) = 0`

Split apart the equation:

`tanx = 0\\cosa = -3`

Solve using the unit circle:

`x = 0, \pi`

`a = [NO--SOLUTION]-- [OUTSIDE--RANGE]`
