Figure 1.1 Linear interpolation  assumes that a straight line joins two points f(a) and f(c), and that the value of f(b), where b lies between a and c, lies on this line. Figure 1.2 Cubic spline interpolation  is when the points f(a) and f(c) are joined by a cubic polynomial, and the value of f(b), a function of b, which lies between points a and c, lies on this curve. Formula Assumes a<b<c f(b)=f(a)+((b-a)/(c-a))[f(c)-f(a)] Example 1 The data was given, shown in Figure 1.1 at right. Figure 2.1 Example 2 In the example on the left, we used linear interpolation to find the freezing temperature of certain salinities of water. 1. Problem Statement Use linear interpolation to determine the freezing temperature of water with a certain salinity. 2. Input/Output Description Inputs: first salinity, second salinity, first freezing temperature, second freezing temperature, new salinity. Output: new freezing temperature 3. Hand Example See...

Lab Today we started with our first Arduino lab. We first wanted to make one LED on a breadboard blink, then get 4 LEDs to blink. I was able to do this successfully using the code below. void setup() {   // put your setup code here, to run once: pinMode(11, OUTPUT); pinMode(10, OUTPUT); pinMode(9, OUTPUT); pinMode(3, OUTPUT); } void loop() {   // put your main code here, to run repeatedly:   digitalWrite(11, HIGH);      delay(500);   digitalWrite(11,LOW);   digitalWrite(10,HIGH);      delay(500);   digitalWrite(10,LOW);   digitalWrite(9,HIGH);      delay(500);   digitalWrite(9,LOW);      delay(100);   digitalWrite(11, HIGH);   digitalWrite(3,HIGH);   digitalWrite(10,HIGH);   digitalWrite(9,HIGH);   delay(100);   digitalWrite(11, LOW);   digitalWrite(3,LOW);   digitalWrite(10,LOW);   digitalWrite(9,LOW); ...

Summary We first learned about the different types of applications of programming to various engineering fields. Then we went over the types of computer languages, which included, machine, assembly, and high-level languages. C and C++, the languages used in this course, are both high-level languages. We were introduced to the engineering problem solving methodology, which is as follows: Problem statement Input/output description Hand example Algorithm development Test solution We then did an activity which utilized this. We got together in groups to perform steps 1-3 in trying to find the distance between two points, then tested this on the computer.  After that, we learned about constants and variables, and about different numeric data types.  Problems 1 //First day //Distance formula program //This program calculates distance between two points #include <stdio.h> #include <math.h> int main(void){ //Declared variables double x1=...
