Frequently Asked Questions
Why am I getting a weird result for sin(90)?
Check your Angle Mode. If the calculator is set to RAD (Radians), sin(90) will calculate the sine of 90 radians. Switch the mode to DEG (Degrees) to get the expected result (which is 1).
What is the difference between 'log' and 'ln'?
log refers to the common logarithm (Base 10). For example, log(100) = 2. ln refers to the Natural Logarithm (Base e). This is commonly used in calculus and physics.
What do nPr and nCr mean?
These are probability functions. nPr (Permutations) calculates possibilities where order matters (e.g., a race). nCr (Combinations) calculates possibilities where order does not matter (e.g., a lottery).
