Algebra and Calculus Problem Solutions
Mathematical Problem Set 1
- Profit Function: P(x) = -4x2 + 632x – 4000, where x > 10 and x is the number of units produced. Find the total production for $800 profit.
Work: 0 = -4x2 + 632x – 4800. Plug into the quadratic formula.
ANS: x = 150 - Relative Maximum: F(x) = ln(2x – 8.4) – 0.25(x + 4)2 + 9.83.
ANS: 10.2 at x = 5.5 - Real Zeros: 3 – 2 log5 √(x2 + 2x + 3), to three decimal places.
ANS: x = -12.091, x = 10.091 - Carbon-14 Dating: A 2,500-year-old estimate of Carbon-14 shows a decrease from 20 grams

Fundamentals of Computers
💻 Introduction to the Computer
A computer is an electronic device that is programmed to accept raw data as input, process it according to a set of instructions (a program), and produce a result (output), which can then be saved for future use (storage). The word “computer” comes from the word “compute,” which essentially means “to calculate.”
Key Characteristics of a Computer
- Speed: Computers can process data at extremely high speeds, measured in microseconds, nanoseconds,
Early Programming Languages and Implementation Methods
FORTRAN
FORTRAN: FORmula TRANslation; scientific computing (arrays, loops, floats); Ideas – compiled code for speed; DO loop; subprograms; formatted I/O. Legacy: foundation of scientific programming.
ALGOL 60
ALGOL 60: ALGOrithmic Language; first machine-independent language; Introduced: block structure, recursion, BNF, format types, compound statements (begin…end); Legacy: basis for imperative languages.

Mastering Python Control Flow: Loops and Conditionals
🐍 Python Loop and Branching Statements
Python provides powerful structures for iteration (loops) and flow control (branching statements) that allow you to execute blocks of code repeatedly or conditionally.
Python Loop Statements
Loops are used to execute a block of code multiple times. The main loop types in Python are while and for.
1. The while Loop
The while loop repeatedly executes a block of statements as long as a given condition is True.
- Syntax:
while condition: # statement(s) to be executed
