Input as dataframe JSON. +- Image (numpy-based): image_stats, image_normalize, image_threshold (input `image_data` JSON array, optional `threshold`). +- Trigonometry: sin, cos, tan, arcsin, arccos, arctan, sinh, cosh, tanh (use `values`, optional `use_degrees`). +- Polynomials: poly_eval, poly_derivative, poly_integral (use `coefficients`, optional `x_values`). + +### `scipy_tool` +- Integrate: integrate_function (operation=`integrate`). +- Optimization: optimize_minimize, optimize_root. +- Interpolation: interpolate_linear / interpolate_cubic / interpolate_spline. +- Special functions: special (function + parameters). +- ODE: solve_ode (expression, initial_conditions, t_values). +- Statistics: statistics/mean/std/describe/ttest/pearsonr via `operation` + `data` (+ `params`). +- FFT: fft, rfft. +- Matrix eigensystem: matrix_eigensystem (uses `matrix_a`). + +## Usage Examples + +```python +from calculator import CALCULATOR_TOOLS + +# Derivative: d(x³)/dx = 3x² +result = CALCULATOR_TOOLS['symbolic_derivative']('x**3', 'x') + +# Solve: x² - 4 = 0 +result = CALCULATOR_TOOLS['solve_equation']('x**2 - 4', 'x') + +# Eigenvalues of matrix +import numpy as np +A = [[1, 2],

Usage Policy + +- Every numeric or symbolic calculation must be delegated to the tools (via MCP `tools/call` or direct `CALCULATOR_TOOLS[...]`), never hand-compute inside the model response. +- Reasoning flow: pick the right tool → prepare JSON-safe inputs → call the tool → present the tool output (with minimal post-processing only for formatting). +- If a step would require arithmetic, call a tool instead (e.g., use `numpy_linear_algebra` for matrices, `symbolic_*` for algebra, `scipy_*` for calculus/optimization). +- Avoid approximations unless the tool returns them; do not estimate values manually. + +### Prompting Playbook (Advanced Problems) +- Restate the task, list the required sub-calculations, and map each to a tool. +- For matrices, always supply `matrix_a` (and `matrix_b` when needed) as JSON arrays to `numpy_linear_algebra`. +- For calculus/ODE/PDE, convert expressions to plain strings (SymPy-compatible) before calling `symbolic_*` or `scipy_*` tools. +- After each tool call, reuse its exact output for subsequent steps—no manual arithmetic in between. +- When summing or solving, prefer tool outputs as inputs to the next tool (e.g., eigenvalues → use in later steps instead of recomputing). +- If the user asks for a result, return: the tool(s) called, inputs used, and the tool outputs; avoid “mental math.” + +## Problem Set + +10 complex university-level problems demonstrating the tool capabilities: + +1. **2nd Order ODE**: y'' + 4y' + 4y = e^x (7 steps) +2. **Eigenvalues & Eigenvectors**: Matrix analysis (5 steps) +3. **Fourier
