I think that this would be the best way to proceed. There's a very simple trig identity that would let you solve it very quickly ...berkeman said:if necessary, I'd look into trig substitutions to help solve it, but you might be able to just do it with triangles.
The equation that needs to be solved in this guide is tan2x + tan x = 0.
The first step is to factor out a common term of tan x from both terms, resulting in tan x(tan x + 1) = 0.
This equation has two solutions since it is a quadratic equation.
You can check your solution by plugging it back into the original equation and verifying that it satisfies the equation.
Yes, this guide provides several expert tips and tricks for solving this equation, such as using the quadratic formula and factoring techniques.
