I've bought a calculus (doesn't specify calc I, II, or II) book and these are the chapters

- Slope of the Tangent Line
- Calculating Derivatives
- Finding Maximum and Minimum Points
- Derivatives of Complicated Functions Derivatives of Trigonometric Functions
- Optimum Values and Related Rates
- The Integral: A Backward Derivative
- Finding Areas with Integrals
- Natural Logarithms
- Exponential Functions and Integration by parts
- Integration by Trigonometric Substitution
- Arc Lengths, Surface Areas, and the Center of Mass
- Introduction to Differential Equations
- Partial Derivatives and Vectors
- Numerical Methods, Taylor Series, and Limits

College-wise are all of these techniques taught in Calculus I? Or do these subjects span over all of Calculus. I'm having a hard time distinguishing a barrier between all of these subjects.
