Mastering the Calculator: A Quick Guide
-
1. Select Your Calculation Mode
Begin by choosing what you need to find. Use the top toggle to switch between
Find Functions(to get values like sin, cos from an angle) andFind Angle(to get an angle from a known ratio like 0.5). -
2. Input Your Value
The active input field will change based on your chosen mode. Enter an angle (in Degrees or Radians) or a numerical ratio. For radian inputs, you can use the handy
πbutton to insert the value of Pi. -
3. Choose Your Units
Select whether your angles are in
DegreesorRadians. When in "Find Angle" mode, this determines the unit of the resulting angle. -
4. View Comprehensive Results
Click "Calculate" to see a full breakdown of results on the right. This includes Primary, Reciprocal, Inverse, and Hyperbolic functions, giving you a complete picture of your input.
Features That Set Us Apart
Dual Calculation Modes
Go beyond standard calculators. Not only can you find the functions of an angle, but you can also find the angle from a function's value—an essential feature for solving trigonometric equations.
Complete Function Set
Get results for all 18 major trigonometric functions. From the standard sine and cosine to their inverses (like arcsin) and hyperbolic counterparts (like sinh), everything is calculated instantly.
Intuitive, Modern UI
Experience a clean, responsive interface that works flawlessly on any device. The "Cosmic Sunset" theme, smooth animations, and glassmorphism design make calculations visually engaging.
Frequently Asked Questions
What is the difference between sin, cos, and tan?
In a right-angled triangle, these are the primary ratios:
- Sine (sin): The ratio of the length of the side Opposite the angle to the length of the Hypotenuse (O/H).
- Cosine (cos): The ratio of the length of the Adjacent side to the length of the Hypotenuse (A/H).
- Tangent (tan): The ratio of the length of the Opposite side to the length of the Adjacent side (O/A).
What are hyperbolic functions (sinh, cosh)?
Hyperbolic functions are analogues of the ordinary trigonometric functions, but defined using the hyperbola rather than the circle. They appear in the solutions to many linear differential equations, such as the equation defining a catenary curve (the shape of a hanging chain).
Why are inverse functions (like asin) "Out of Domain" for some values?
The output of the standard sine and cosine functions can only ever be a value between -1 and +1. Therefore, you cannot take the inverse sine (arcsin) or inverse cosine (arccos) of a number outside of this range. Our calculator shows "Out of Domain" to reflect this mathematical rule.
