The 10 Most Important Patterns

Pattern English Usage Example
α alpha Variables, angles α_max = 100
β beta Parameters β_function(x)
γ gamma Growth rate γ_correction = 0.1
λ lambda Functions λx: x²
∑ sum Aggregation ∑(i=1 to n) x_i
→ to Direction x → y
⇒ implies Logic flow x ⇒ y
≠ not_equal Comparison x ≠ y
∞ infinity Unbounded limit → ∞

Practice These First

# Basic greeting
α! β! γ! → alpha! beta! gamma!

# Simple math
∑(i=1 to 5) i → sum of i equals 1 to 5

# Function definition  
λx: x² → lambda x: x squared

# Logic flow
input → validate → process → output

# Robot emotions
😺 happy_cat → 😺 任务完成！

📱 Using the Interface

Main Features

Quick Examples (Click to Try!)

Greek Letters:     α! β! γ! → alpha! beta! gamma!
Mathematical:      ∑∏∫ → λ≠∞   → sum product integral to lambda not equal infinity
Programming:       λ≤≥∞ → λ√°′²    → lambda less equal greater equal infinity to lambda square root degrees prime squared
Emotional:        😺😸😹 → 😺😸😹 → happy_cat grinning_cat joy_cat
Complex:          α! β! γ∇data.μ_.σ() → alpha! beta! gamma transform data mu sigma()

Real-world Examples

# Robot Communication
Temperature: T = 25°C → Temperature: T = 25 degrees Celsius
Movement: pos → ∇path → pos = to gradient path

# Mathematics  
Derivative: f′(x) = lim(h→0) [f(x+h)-f(x)]/h → f prime of x equals limit h to 0 of f of x plus h minus f of x divided by h
Integration: ∫f(x)dx = F(x) + C → integral of f of x dx equals capital F of x plus C

# Computer Science
Algorithm: O(n log n) → big O of n log n
Data: x ∈ S → x in S
Logic: ∀x∈S: P(x) → for all x in S: P of x

# AI/ML
Neural Net: h = σ(Wx + b) → h equals sigma of W x plus b
Loss: L = -∑y·log(p) + λ∥θ∥² → L equals negative sum y log p plus lambda norm theta squared
