Frequently asked questions
What is the domain for arcsine and arccosine functions?
Arcsine and arccosine accept input values between -1 and 1 only, as these represent valid sine and cosine ratios.
What's the difference between degrees and radians output?
Degrees use a 360° scale while radians use a 2π scale. Radians are preferred in advanced mathematics and calculus.
Can I calculate inverse tangent for any value?
Yes, arctangent accepts any real number as input since tangent ratios can range from negative infinity to positive infinity.
