Introduction
Tangent Calculator — Compute the tangent of an angle in degrees. Enter Angle (degrees) to get an instant, accurate result.
Formula
tan(angle) = sin(angle)/cos(angle), with the input angle in degrees converted to radians before evaluation.
Step-by-step
- Enter the Angle (degrees).
- Click Calculate to see your result instantly.
Real-world example
Example: With Angle (degrees) = 45, the Tangent Calculator gives Result: 1.
Frequently Asked Questions
What happens at 90°?
Tangent is undefined there since cosine is 0 — the result becomes extremely large rather than a finite number.
Is the input in degrees?
Yes.
What inputs does the Tangent Calculator need?
You'll need to provide: Angle (degrees). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Tangent Calculator?
The Tangent Calculator applies the formula exactly as calculated — tan(angle) = sin(angle)/cos(angle), with the input angle in degrees converted to radians before evaluation. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Tangent Calculator free to use?
Yes, the Tangent Calculator is completely free, requires no signup, and runs instantly in your browser.
About the Tangent Calculator
The Tangent Calculator uses a real, verifiable formula — tan(angle) = sin(angle)/cos(angle), with the input angle in degrees converted to radians before evaluation. — so results are accurate every time, not an approximation.
