Taylor expansion definition of the exponential function

🔗
The Taylor series expansion is the most direct definition of the expontial as it obviously satisfies the exponential function differential equation:
• the first constant term dies
• each other term gets converted to the one before
• because we have infinite many terms, we get what we started with!
$$ex=∑n=0∞​n!xn​=1+1x​+2x2​+2×3x3​+2×3×4x4​+… (70)$$
