Tangent Calculator

Looking for a simple and accurate way to calculate the tangent of any angle in degrees or radians? Our Tangent Calculator gives instant results with just one click. Whether you’re solving trigonometry problems, working on physics equations, or dealing with real-world applications in engineering and navigation, this tool saves you time and provides error-free results every time.

Understanding the Tangent Function

🔹 What is Tangent (tan θ)?
The tangent function is a fundamental trigonometric function. It represents the ratio of the opposite side to the adjacent side in a right-angled triangle.
Formula: tan θ = Opposite / Adjacent
Range: -∞ < tan θ < +∞ (except undefined values where cos θ = 0)
Tangent is widely used in geometry, physics, navigation, engineering, and computer graphics to model slopes, angles, and wave patterns.

🔹 Degrees vs Radians
Angles can be measured in two different ways:
• Degrees (°): Common in geometry, classrooms, and day-to-day calculations (e.g., 30°, 45°, 75°).
• Radians (rad): Standard in advanced mathematics and physics (e.g., 0.52 rad, 0.79 rad, 1.57 rad).
Our Tangent Calculator works perfectly in both degrees and radians, giving you full flexibility.

Formula for Calculating Tangent

Since tangent is undefined whenever cos θ = 0, angles like 90°, 270° (or π/2, 3π/2 in radians) must be avoided.
Instead of memorizing trigonometric tables or doing manual calculations, you can simply enter an angle into our calculator and get the tangent instantly.

Examples of Tangent Calculations

Example: tan 0°

✅ So, the tangent of 0 degrees is 0

Example: tan 0.5 radians

✅ So, the tangent of 0.5 radians is approximately 0.5463

Example: tan 45°

✅ So, the tangent of 45 degrees is exactly 1

Example: tan 1.2 radians

✅ So, the tangent of 1.2 radians is approximately 2.5721

Example: tan 60°

✅ So, the tangent of 60 degrees is approximately 1.7321

Example: tan 2 radians

✅ So, the tangent of 2 radians is approximately -2.1850

Why Use an Online Tangent Calculator?

Manual tangent calculations can be tricky, especially for large angles or when switching between degrees and radians. Scientific calculators require checking modes, pressing multiple buttons, and still risk errors.
Our Tangent Calculator eliminates these problems by giving you fast, precise, and reliable results instantly. Just enter the angle, choose degrees or radians, and hit calculate—your answer is ready.
