Core Functions and Formulas Used in a Sci Calculator

1. Arithmetic Operations

Plain Text Formulas:

Addition: a + b
Subtraction: a − b
Multiplication: a × b
Division: a ÷ b

Example:

15 + 32 = 47
50 − 18 = 32
7 × 6 = 42
100 ÷ 4 = 25

2. Exponents and Powers

Formula (Plain Text):
y = x^n

Example:

3^4 = 3 × 3 × 3 × 3 = 81

3. Roots

Formula (Plain Text):

Square root: √x
Cube root: ∛x
nth root: x^(1/n)

Example:

√49 = 7
∛27 = 3
16^(1/4) = 2

4. Trigonometric Functions

Formulas (Plain Text):

sin θ, cos θ, tan θ
arcsin(x), arccos(x), arctan(x)

Example:

sin 30° = 0.5
cos 60° = 0.5
tan 45° = 1

5. Logarithmic Functions

Formulas (Plain Text):

log10(x) = logarithm base 10
ln(x) = natural logarithm (base e)

Example:

log10 100 = 2
ln e = 1

6. Factorials

Formula (Plain Text):
n! = n × (n − 1) × (n − 2) × … × 1

Example:

5! = 5 × 4 × 3 × 2 × 1 = 120

7. Combinations and Permutations

Formulas (Plain Text):

Permutations: P(n, r) = n! / (n − r)!
Combinations: C(n, r) = n! / [r! × (n − r)!]

Example:

P(5, 2) = 5 × 4 = 20
C(5, 2) = 5 × 4 ÷ (2 × 1) = 10
