Study Notes
Mechanics and Properties of Matter
- PHY 102 is a course that covers introductory mechanics and properties of matter.
- The course is taught by Prof. O.E. Awe and Dr. Titus Ogunseye.
- Recommended textbooks include "Fundamentals of Physics" by Resnick and Halliday, "Advanced Level Physics" by Nelkon and Parker, and "College Physics" by any good author.
Useful Mathematics
- The physical world has an underlying order, which allows for accurate predictions of physical systems using laws and theorems.
- Laws and theorems can be expressed as mathematical functions, which can be represented in various forms: tables, formulas, and graphs.
Periodic and Sinusoidal Functions
- Periodic functions repeat their values at regular intervals.
- Examples of periodic functions include trigonometric functions, inverse trigonometric functions, and hyperbolic functions.
- A special integration is ∫dx = loge x + c.
- When a quantity can assume any value (not just integers), we say it is continuous, and summation is replaced by integration.
Application of Integration
- The area of a circle can be calculated by integrating the areas of tiny rings that make up the circle.
- The formula for the area of a circle is A = πr^2.
- The surface area of a sphere is 4πr^2, and the volume of a sphere is (4/3)πr^3.
Sinusoidal Functions
- A function based on the sine function, which oscillates between minimum and maximum values at regular intervals, is known as a sinusoidal function.
- Both sine and cosine functions are examples of sinusoidal functions.
- The graph of either sine or cosine function is known as a sinusoidal wave.
- Examples of sinusoidal waves include AC voltage, AC current, simple harmonic motion, and displacement in wave motion.
Logarithm Functions and Indices
- The logarithm function is defined as y = logb x, where b is the base of the logarithm.
- The exponential function is defined as x = b^y.
- The natural logarithm is a logarithm with base e (approximately 2.7183).
- The natural logarithm is used in many natural systems, such as exponential functions.
Derived Functions and Differentiation
- Linear equations have a constant rate of change, while nonlinear equations have a varying rate of change.
- The derivative of a function represents the rate of change of the function with respect to its variable.
- The differentiation operation can be applied repeatedly to find higher-order derivatives.
- The derivative of y = kx^n is (nk)x^(n-1).
