WHY PROBLEM SOLVING? • Problem solving is the most basic of mathematical skills- the reason for studying mathematics • Problem solving is an integral part of the larger area of critical thinking‚ which is universally accepted goal for all education • Problem solving shows an interaction between mathematical ideas • In the classroom can lessen the gap between real world problem and the classroom worlds and thus set more positive mood in the classroom. WHAT IS PROBLEM? The

multiple of d: 58237 = 58168・5869 (recall the rule for exponents: abac = ab+c). Therefore 58237 = 58168・5869 + 0 and we have q = 5869 and r = 0. (6) Q #2: a) Prove the following: ∃ an even integer n that can be written in two ways as a sum of two prime numbers. Solution: Let n = 14. Then 14 = 11 + 3 = 7 + 7 and 3‚ 7‚ and 11 are all prime numbers. b) Suppose that r and s are integers. Prove the following: ∃ an integer k such that 22r + 18s = 2k. Solution: Let k = 11r + 9s

1. INTRODUCTION 1. OVERVIEW In order to achieve several small scale and large scale objectives in various electronic circuits‚ it is highly essential to regulate the voltage supply‚ given to electronic circuits. This project‚ namely VARIABLE VOLTAGE REGULATOR‚ aims at fulfilling such small goals‚ using the 3-terminal voltage regulator LM317. The circuit consists of an IC LM317 and a set of resistors and capacitors‚ in addition to the transformer and the rectifying element. The AC

best solution in problems What are problem solving blocks? A block is anything which prevents us finding an effective solution to a problem. We all experience them‚ but of different types and intensities. The blocks have been grouped in various ways by different authors according to their cause‚ eg perceptual emotional intellectual expressive environmental cultural It’s important that you are able to recognise when blocks are hindering your problem solving so that you can take action to overcome them

Mixing Problems 1. All of the mixing problems that we will be dealing with will involve a “tank”.(mixing fluids in a tank) Problem: Consider a tank which initially holds V0 gal of brine that contains a lb of salt. Another brine solution containing b lb of salt/gallon is poured into the tank at rate of gal/min‚ while simultaneously‚ the well-stirred solution leaves the tank at a rate of f gal/min Objective: Find the amount of salt in the tank at any time t 2.

Unit 4 Research Paper Assignment 1: Using Global Variables 1. Five advantages of using global variables • It is accessible to all modules in a program • You only have to declare it once outside the modules • It is good to use it for constants you want to keep consistent • It simplifies maintenance‚ avoids duplication of local constants • It can make a program easier to read in reference to constants Five disadvantages of using global variables • It makes debugging difficult • Any statement
