GP program Use to solve and display geometric sequences. Enter known first term and common ratio or any two terms of the sequence. Solves for terms and sums of GP's backwards and forwards and also sum to infinity. HERON program. Use to find semi-perimeter and area of triangle given all three side lengths. Use to solve distance problems on surface of earth given latitudes and longitudes.
Use to generate n terms of sequence of prime, square, triangle or Fibonacci numbers. PRIME program. Use to find if n is prime. Returns smallest factor if composite. Use to find the prime factorisation of n. Use to convert between expanded, factored and completed square forms of any quadratic and find roots even if complex. REPAY program. For example:. That Quadratic Formula sure is a pain to memorize, but it makes it really easy to program a calculator to solve quadratic equations for you.
Forget about solving by factoring and completing the square. Just use this program. Casio's download site has lots more programs including programs similar to the above for loading right into your calculator. Casio's documentation ftp site - Go here for all the manuals.
Casio Calculator Bug - Beware this bug in the Casio calculators. It places side-by-side multiplication e. The workaround for this is to avoid side-by-side multiplication. This set of programs was written for the Western Australian Calculus course. Preview Enter complex number z in either cartesian or polar form and then convert between forms, find n th power, list n th roots and evaluate e z.
Preview Dot product of two vectors. Preview Displays exact values of sin, cos and tan from 0 to degrees. Preview First store f x in Y1. See Task 5 - Investigating when the iteration fails. Divides any two polynomials, returning quotient and remainder. See Sheet 11 for worked examples. CFXG version. See Sheet 12 for worked example. Multiplies any two polynomials any order together. See Sheet 12 for help. Solutions displayed in rows with first column degrees, second column radians and third column exact multiples of pi where possible.
This set of programs was written for the Western Australian Applicable Mathematics course. Also has copy of MAV. Preview Gaussian elimination of matrix A, result in matrix R, showing steps. Preview Solves linear programming problems. Enter inequalities, objective function and program does the rest. Finds the median from a grouped frequency table using linear interpolation. See Sheet 15 for a worked example.
Five probability distributions in one quick program. Calculate, tabulate and plot any normal, exponential, Binomial, Poisson or user defined any pdf entered in Y1 probabilities. Probabilities now displayed to 5dp instead of 4! Check your regression model with this small utility which calculates and plots residuals based on regression of List 2 y on List 1 x.
Preview Reduces matrix A to echelon form, storing result in matrix R and indicating type of solution. Though rarely shows a neat path to the reduction! Enter coordinates of two points and get gradient, midpoint, distance and equation of line. Works out aerobic exercise heart rate targets for given age, exercise intensity and level of fitness. Solves latitude and longditude problems - both distance from A to B or position after travelling x km from A.
Little utility to calculate mean and median for single data set without going into STAT mode. Enter quadratic in any form and have it converted into standard, completed square and factored where possible forms. Roots real or complex given as both exact and decimal values. Solves surface area and volume problems for most prisms, pyramids, cones, spheres and cylinders. Preview Simplifies several common types of surd expressions.
Introduction to finding area beneath a curve using trapeziums. Store function in Y1 first. Uses Lists 1 to 3 for working.
