Deductive validity, a argument is deductively valid when it is impossible that its conclusion is incorrect -If premises are true is the conclusion true? Yes = deductive (If I am in chch then I am in NZ 2. I am in chch 3. I am in NZ) deductively valid and Affirming antecedent
Modus ponens (affirming the antecedent) , called this because if x then consequence.....If P then Q -If there is no petrol in the car then the car wont run. The car wont run. So there is no petrol in the car. - Modus Tollens
## 48. Measures of Central Tendency and Dispersion
### a) Measures of Central Tendency
These metrics identify the central point of a data distribution.
* **Mean (Average):** The sum of all values divided by the count.
* *Example:* A retail store counts daily customers over 5 days: [10, 15, 20, 25, 30]. The Mean is \frac{10+15+20+25+30}{5} = 20.
* **Median (Middle Value):** The middle number in a sorted list. It is highly resistant to outliers.
* *Example:* If software engineer salaries...

DC GENERATOR
A DC generator works on the principle of electromagnetic induction. When a conductor moves in a magnetic field and cuts magnetic flux, an electromotive force is induced in it. Thus, a DC generator converts mechanical energy into electrical energy.
The main parts of a DC generator are the yoke, pole core, field winding, armature core, armature winding, commutator, and brushes. The yoke provides mechanical support, while the field windings produce the magnetic field.
a) Let f:R→Rf:\mathbb{R}\rightarrow\mathbb{R}f:R→R be defined by f(x)=sinxf(x)=\sin xf(x)=sinx
(i) Find the image set of R\mathbb{R}R under fff and conclude whether fff is surjective.
Given f(x)=sinxf(x)=\sin xf(x)=sinx For every real number xxx,
−1≤sinx≤1-1\leq \sin x\leq 1−1≤sinx≤1
Hence the image set is f(R)={y:y=sinx, x∈R}f(\mathbb{R})=\{y:y=\sin x,\;x\in\mathbb{R}\}f(R)={y:y=sinx,x∈R} ={y:−1≤y≤1}=\{y:-1\leq y\leq1\}={y:−1≤y≤1} f(R)=[−1,1]...
