- Inequalities are mathematical expressions involving comparison symbols like >, <, ≥, ≤. Solving an inequality means finding the range of values for an unknown that satisfy the inequality.
- Inequalities can be solved using algebra or graphs. When solving algebraically, the same rules apply as with equations except when multiplying or dividing by a negative number, the inequality sign must be reversed.
- Graphs can also be used to solve inequalities by sketching the graph of the expression and finding where it cuts the x-axis and identifying where the expression is positive or negative.
This document shows that adding single digit numbers to products of numbers and those same single digits results in patterns, such as 987654321. It then provides a formula to assign numeric values to letters of the alphabet. Using this formula, it shows that the words HARD WORK and KNOWLEDGE equal 98% and 96% respectively, while ATTITUDE equals 100%. Finally, it demonstrates that LOVE OF GOD equals 101%, indicating with mathematical certainty that the love of God can help one achieve more than what is normally considered 100%.
This document contains lecture notes on evaluating definite integrals. It introduces the definition of the definite integral as a limit of Riemann sums, and properties of integrals such as additivity and comparison properties. It also states the Second Fundamental Theorem of Calculus, which relates definite integrals to indefinite integrals via the derivative of the integrand function. Examples are provided to illustrate how to use these properties and theorems to evaluate definite integrals.
The document discusses kinematics concepts including distance, displacement, speed, velocity, and acceleration. It defines distance as the total length of a path traveled and displacement as the straight-line distance between initial and final positions. Speed is the distance traveled per unit time and is a scalar quantity, while velocity is displacement per unit time and has both magnitude and direction. Acceleration is the rate of change of velocity with respect to time and occurs when a force acts on an object. Formulas for average and instantaneous velocity and acceleration are presented for motion with constant acceleration. Examples apply these concepts to problems involving cars, runners, airplanes, and balls on inclines.

Here are the steps to solve the equations and graph them:
1. x2 + 4 = 0
x2 = -4
x = ±2i
Graph: The graph is the imaginary axis.
2. 2x2 + 18 = 0
2x2 = -18
x2 = -9
x = ±3i
Graph: The graph is the imaginary axis.
3. 2x2 + 14 = 0
2x2 = -14
x2 = -7
x = ±√7i
Graph: The graph is the imaginary axis.
4. 3x2 + 27 = 0
3x2 = -27
x2 = -
This document is the introduction to a series of lectures on general physics. It discusses how humans have been curious about nature since the beginning of creation on Earth and sought to understand the existence and reasons behind phenomena. While early humans attributed natural phenomena to supernatural forces out of ignorance, the development of rational thought and observation led to the realization that nature is governed by interconnected laws. The study of physics helps humans understand how God created the ordered and harmonious universe, both the living and non-living worlds, and their interrelation with human activities.
