How do I use Formula Pro?
Formula Pro is a calculator that can handle a wide range of mathematical operations. Here's a quick guide to get you started.
Basic Operations
- • Addition:
2 + 2 - • Subtraction:
5 - 3 - • Multiplication:
4 * 3or4(3) - • Division:
10 / 2 - • Exponents:
2^3
Special Functions
- • Square root:
sqrt(16) - • nth root:
nthrt(8, 3) - • Trigonometry:
sin(pi/2),cos(pi),tan(pi/4) - • Logarithms:
log(100),ln(e) - • Absolute value:
abs(-5)or|-5| - • Round:
round(3.14159). Specify a second argument to round to a specific decimal place. For example,round(3.14159, 2)rounds to 2 decimal places.
Variables
- • Assignment:
x = 5 - • Usage:
y = 2x + 3 - • Multiple variables:
z = x + y
Vector Operations
- • Create a vector:
[1, 2, 3] - • Statistical operations:
- - Mean:
mean([1, 2, 3, 4])→ 2.5 - - Median:
median([1, 2, 3, 4])→ 2.5 - - Standard deviation:
std([1, 2, 3, 4])→ 1.29 - - Total:
total([1, 2, 3, 4])→ 10 - - Range:
range(1, 5)→ [1, 2, 3, 4] - - Flatten:
flat([1, 2, 3, 4])→ [1, 2, 3, 4] - - Zeros:
zeros(3, 4)→ [[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]] - - Ones:
ones(3, 4)→ [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]] - - Random:
rand(1, 5)→ 3 - - Random integer:
randi(1, 5)→ 3
- - Mean:
- • Vector manipulations:
- - Length:
len([1, 2, 3, 4])→ 4 - - Sort:
sort([3, 1, 4, 2])→ [1, 2, 3, 4] - - Dot product:
dot([1, 2], [3, 4])→ 11
- - Length:
