Frequently Asked Questions
What are inverse trigonometric functions?
Inverse trigonometric functions (arcsin, arccos, arctan) are the inverse operations of sine, cosine, and tangent. They help find angles when given trigonometric ratios, essentially answering "what angle has this trigonometric value?"
What is the domain of arcsin and arccos?
The domain of arcsin and arccos is [-1, 1]. Input values outside this range are undefined for these functions because sine and cosine values cannot exceed 1 or be less than -1. Our calculator will show an error for invalid inputs.
What is the range of inverse trigonometric functions?
Each inverse function has a specific range: arcsin returns values in [-π/2, π/2] or [-90°, 90°], arccos returns values in [0, π] or [0°, 180°], and arctan returns values in (-π/2, π/2) or (-90°, 90°). These ranges ensure unique results.
How do I convert between degrees and radians?
To convert radians to degrees, multiply by 180/π (approximately 57.2958). To convert degrees to radians, multiply by π/180 (approximately 0.0175). Our calculator automatically shows results in both units for convenience.
Is this inverse trigonometric calculator free?
Yes, our inverse trigonometric functions calculator is completely free to use with unlimited calculations, no registration required, and no hidden fees. All features including high precision calculations and result downloads are available at no cost.
What is the difference between arctan and atan2?
Arctan takes one argument and returns values in (-π/2, π/2), while atan2 takes two arguments (y, x) and returns values in (-π, π], providing full quadrant information. Our calculator focuses on the standard single-argument inverse functions.
How accurate are the calculations?
Our calculator uses JavaScript's built-in Math functions which provide double-precision floating-point accuracy (approximately 15-17 decimal digits). You can adjust the display precision from 2 to 10 decimal places based on your needs.
