A surd is an irrational number that includes a radical symbol and cannot be calculated exactly. Surd laws allow for simplifying expressions involving surds through operations like multiplication, division, and exponentiation. Surds can be added or subtracted if they have the same radical term, but expressions involving unlike surds cannot be fully simplified. Examples demonstrate working through surd arithmetic problems step-by-step using surd laws and properties.
1. The document discusses coordinate planes and identifying points using ordered pairs. It provides examples of ordered pairs and asks the reader to identify other coordinates.
2. It then discusses a vertical line l that passes through the point (3,7) and asks the reader to find 6 points on the line and 6 points not on the line, as well as how to tell if a point is on the line based on its coordinates.
3. Finally, it introduces transformations on coordinate planes and asks the reader questions about finding points with specific x- and y-coordinates or where the y-coordinate is less than the x-coordinate. It provides homework problems for further practice.
The document discusses differentiating exponential functions. It introduces the derivative rule for exponential functions as the derivative of a function f(x) = a^x is f'(x) = a^x * ln(a). This shows that the derivative of an exponential function is the function itself multiplied by the natural log of its base. It then examines this concept numerically and symbolically, showing the relationship between exponential functions with different bases and their derivatives.

The document discusses rationalizing denominators through four examples:
1) (i)^2 is rationalized to 4/2 = 2
2) (ii)^3/2 is rationalized to 3√5/√5
3) (iii)/(2-1) is rationalized to 3√2+3/(2-1)
4) (iv)/(2-3) is rationalized to (2+3)(2+3)(2+3)/(4-3)
The document provides instructions for simplifying algebraic fractions. It states that one should always factorize the expression first before cancelling terms. Several worked examples are provided that show the steps to (1) create a common denominator, (2) identify the difference between the old and new denominators, and (3) multiply the numerator by this difference when factorizing.
The document discusses how to solve equations by making the variable the subject of the formula. It provides examples of solving equations such as x + 3 = 6, 5z = 45, and 4(a - 5) = 16 for the variable.

It provides examples of solving inequalities like 6x < 36 and -4 ≤ -4x ≤ 8.
The document provides information on index laws and the meaning of indices in algebra:
- Index laws state that am × an = am+n, am ÷ an = am-n, and (am)n = amn. Exponents can be added or subtracted when multiplying or dividing terms with the same base.
- Positive exponents indicate a term is raised to a power. Negative exponents indicate a root is being taken. Terms with exponents are evaluated from left to right.
- Examples demonstrate how to simplify expressions using index laws and interpret different types of indices.
The document discusses solving inequalities involving quadratic and rational expressions. For quadratic inequalities, it explains how to factorize, set each factor equal to zero to find critical values, and use these to determine intervals where the parabola is above or below the x-axis. For rational inequalities, it outlines steps to find where the denominator is zero, solve the resulting equality, plot critical values on a number line, and test intervals to determine the solution set. The document provides examples demonstrating these techniques.

- Odd degree polynomials must have at least one real root.
- Examples of factorizing polynomials over both real and complex numbers are provided.
The document describes the Trapezoidal Rule for approximating the area under a curve between two points. It shows that the area A is estimated by dividing the region into trapezoids with height equal to the function values at the interval endpoints and bases equal to the intervals. In general, the area is approximated as the sum of the areas of each trapezoid, which is equal to the average of the endpoint function values multiplied by the interval length.
The document discusses methods for calculating the volumes of solids of revolution. It provides formulas for finding volumes when an area is revolved around either the x-axis or y-axis. Examples are given for finding volumes of common solids like cones, spheres, and others. Steps are shown for using the formulas to calculate volumes based on given functions and limits of revolution.
The document discusses different methods for calculating the area under a curve or between curves.
(1) The area below the x-axis is given by the integral of the function between the bounds, which can be positive or negative depending on whether the area is above or below the x-axis.
(2) To calculate the area on the y-axis, the function is solved for x in terms of y, then the bounds are substituted into the integral of this new function with respect to y.
(3) The area between two curves is calculated by taking the integral of the upper curve minus the integral of the lower curve, both between the same bounds on the x-axis.
The document discusses 8 properties of definite integrals:
1) Integrating polynomials results in a fraction.
2) Constants can be factored out of integrals.
3) Integrals of sums are equal to the sum of integrals.
4) Splitting an integral range results in the sum of the integrals.
5) Integrals of positive functions over a range are positive, and negative if the function is negative.
6) Integrals can be compared based on the relative values of the integrands.
7) Changing the limits of integration flips the sign of the integral.
8) Integrals of odd functions over a symmetric range are zero, and integrals of even functions are twice the integral over

The document discusses the relationship between integration and calculating the area under a curve. It shows that the area under a curve from x=a to x=b can be calculated as the integral from a to b of the function f(x) dx. This is equal to the antiderivative F(x) evaluated from b to a. The area under a curve can also be estimated using rectangles, and as the width of the rectangles approaches 0, the estimate becomes the exact area. The derivative of the area function A(x) gives the equation of the curve f(x). Examples are given to calculate the exact area under curves.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
