2 tan (4*x) + tan(4*x) = 0
$$\tan^{2}{\left(4 x \right)} + \tan{\left(4 x \right)} = 0$$
Detail solution
Given the equation:
$$\tan^{2}{\left(4 x \right)} + \tan{\left(4 x \right)} = 0$$
Transform
$$\tan^{2}{\left(4 x \right)} + \tan{\left(4 x \right)} = 0$$
$$\left(\tan{\left(4 x \right)} + 1\right) \tan{\left(4 x \right)} = 0$$
Consider each factor separately
$$\tan{\left(4 x \right)} + 1 = 0$$
- this is the simplest trigonometric equation
Move $1$ to right part of the equation
with the change of sign in $1$
We get:
$$\tan{\left(4 x \right)} = -1$$
This equation is transformed to
$$4 x = \pi n + \operatorname{atan}{\left(-1 \right)}$$
Or
$$4 x = \pi n - \frac{\pi}{4}$$
, where n - is a integer
Divide both parts of the equation by
$$4$$
get the intermediate answer:
$$x = \frac{\pi n}{4} - \frac{\pi}{16}$$
$$\tan{\left(4 x \right)} = 0$$
- this is the simplest trigonometric equation
We get:
$$\tan{\left(4 x \right)} = 0$$
This equation is transformed to
$$4 x = \pi n + \operatorname{atan}{\left(0 \right)}$$
Or
$$4 x = \pi n$$
, where n - is a integer
Divide both parts of the equation by
$$4$$
get the intermediate answer:
$$x = \frac{\pi n}{4} - \frac{\pi}{16}$$
$$x = \frac{\pi n}{4}$$
The final answer:
$$x_{1} = \frac{\pi n}{4} - \frac{\pi}{16}$$
$$x_{2} = \frac{\pi n}{4}$$
$$\tan^{2}{\left(4 x \right)} + \tan{\left(4 x \right)} = 0$$
Transform
$$\tan^{2}{\left(4 x \right)} + \tan{\left(4 x \right)} = 0$$
$$\left(\tan{\left(4 x \right)} + 1\right) \tan{\left(4 x \right)} = 0$$
