Introduction

The equation $\tan^2 x - 3 = 0$ is a trigonometric equation that involves the tangent function. In this article, we will solve this equation and find all possible solutions in radians in terms of $\pi$. We will use various trigonometric identities and properties to simplify the equation and find its solutions.

Understanding the Equation

The given equation is $\tan^2 x - 3 = 0$. This equation involves the tangent function, which is defined as the ratio of the sine and cosine functions. The tangent function is periodic with a period of $\pi$, meaning that the graph of the tangent function repeats every $\pi$ units.

Simplifying the Equation

To simplify the equation, we can start by adding 3 to both sides of the equation, which gives us:

$$\tan^2 x = 3$$

Using Trigonometric Identities

We can use the trigonometric identity $\tan^2 x = \sec^2 x - 1$ to rewrite the equation as:

$$\sec^2 x - 1 = 3$$

Simplifying Further

We can simplify the equation further by adding 1 to both sides, which gives us:

$$\sec^2 x = 4$$

Finding the Solutions

We can find the solutions to the equation by taking the square root of both sides, which gives us:

$$\sec x = \pm 2$$

Using the Definition of Secant

We can use the definition of the secant function, which is the reciprocal of the cosine function, to rewrite the equation as:

$$\frac{1}{\cos x} = \pm 2$$

Simplifying Further

We can simplify the equation further by taking the reciprocal of both sides, which gives us:

$$\cos x = \pm \frac{1}{2}$$

Finding the Solutions

We can find the solutions to the equation by using the unit circle and the properties of the cosine function. The cosine function is positive in the first and fourth quadrants, and negative in the second and third quadrants.

Solutions in the First Quadrant

In the first quadrant, the cosine function is positive, so we have:

$$\cos x = \frac{1}{2}$$

Solutions in the Second Quadrant

In the second quadrant, the cosine function is negative, so we have:

$$\cos x = -\frac{1}{2}$$

Solutions in the Third Quadrant

In the third quadrant, the cosine function is negative, so we have:

$$\cos x = -\frac{1}{2}$$

Solutions in the Fourth Quadrant

In the fourth quadrant, the cosine function is positive, so we have:

$$\cos x = \frac{1}{2}$$

Finding the Values of x

We can find the values of x by using the inverse cosine function, which is denoted by $\cos^{-1}$. We can use a calculator or a trigonometric table to find the values of x.

Solutions in Radians

We can find the solutions in radians by using the values of x that we found earlier. We can express the solutions in terms of $\pi$ by using the fact that the cosine function is periodic with a period of $2\pi$.

Example Solutions

Here are some example solutions to the equation:

• $x = \frac{\pi}{6} + 2k\pi, k \in \mathbb{Z}$
• $x = \frac{5\pi}{6} + 2k\pi, k \in \mathbb{Z}$
