Update 3

• Explain linear approximation and the concept of the derivative being the best approximation of a function near a point
• Conditions for differentiability
• Polar coordinates
• Parametric equations
• Properties of limits
• Notation of derivatives
• Explains derivatives of higher orders
• Chain rule
• Where to add transcendental functions?
• Explain the notation dy/dx (guidorizzi has it)
• Limits at infinity, explain better than "Because x^2 grows without limits"
• Properties of derivatives
• Max and min
• It may be wrong to say "for each epsilon", check that
