The Derivatives Nature Chose: sin, cos, eˣ, ln

Name: The Derivatives Nature Chose: sin, cos, eˣ, ln
Description: Sine's derivative is cosine; eˣ is its own derivative. These are not coincidences — they are why these functions matter.

Each chapter closes with capabilities, not topics. Watch for these.

01Justify the derivatives of sin x and cos x geometrically

02Explain e as the base whose exponential equals its own derivative

03Use d/dx ln x = 1/x
