Scientific Calculator With Normal/Gaussian Distribution 2.0

F-Graph offers a robust set of features for calculating and plotting the standard normal distribution frequency and density functions. It enables users to analyze one-tailed, two-tailed, and cumulative density functions alongside the raw frequency function.

The application allows for direct input of Z values corresponding to the standard normal distribution N(0,1), as well as X values pertaining to any normal distribution N(m, s). When entering X values, the user must provide the mean (m) and standard deviation (s). Conversely, inputting Z values will yield corresponding X values based on the specified parameters.

In addition to its statistical capabilities, F-Graph serves as a scientific calculator. Users can initiate calculations either by interacting with the application’s interface or by entering text expressions directly. The calculator can handle multiple levels of parentheses, with automatic closing brackets added upon pressing function buttons. Subsequently, users can enter the necessary arguments to complete their calculations.

Notable supported functions include:

• ln(X): natural logarithm
• log(X): logarithm base 10
• log2(X): logarithm base 2
• exp(X): e raised to the power of X
• rtod: converts radians to decimal degrees
• dtor: converts decimal degrees to radians
• sqrt(X): square root of X
• nthroot(X, N): Nth root of X
• pow(N, X): N raised to the power of X
• All standard trigonometric functions, with arguments provided in radians
