Solve the four problems. For problem 4, discuss a project you would want to see done in your homeschool coop, church, or community. Day 17 Create a proposal. If you wrote a proposal, still present it without reading it.
One should first calculate the denominator and stop early if it is zero possibly adding code to detect colinearity. Next, instead of calculating s and t directly, test the relationship between the two numerators and the denominator. Only if the lines are confirmed to intersect do you actually need to calculate the value of t but not s.
Do two lines from A to B and from C to D intersect? Then you can ask it four times between the line and each of the four sides of the rectangle. My notation is that Ax is the "x-coordinate of A" and Cy is the "y-coordinate of C.
If h is exactly 0 or 1 the lines touch at an end-point. You can consider this an "intersection" or not as you see fit.
Specifically, h is how much you have to multiply the length of the line in order to exactly touch the other line. A and C are vectors that point to the start of the line; E and F are the vectors from the ends of A and C that form the line.
For any two non-parallel lines in the plane, there must be exactly one pair of scalar g and h such that this equation holds: Because two non-parallel lines must intersect, which means you can scale both lines by some amount each and touch each other. At first this looks like a single equation with two unknowns!
We have to eliminate one of these variables. An easy way is to make the E term zero. To do that, take the dot-product of both sides of the equation using a vector that will dot to zero with E. That vector I called P above, and I did the obvious transformation of E.Write a program that reads a file, breaks each line into words, strips whitespace and punctuation from the words, and converts them to lowercase.
Modify your program from the previous exercise to read the book you downloaded, skip over the header information at the beginning of the file, and process.

Abstract. The proper understanding and use of statistical tools are essential to the scientific enterprise.
This is true both at the level of designing one's own experiments as well as for critically evaluating studies carried out by others. Abstract.
The variety of available techniques and analytical methods applied in laboratories calls for the need of defining the scope, range of application and quality of information obtained using each of them with reference to internationally agreed standards.
The point slope form of a linear equation is written as.
In this equation, m is the slope and (x 1, y 1) are the coordinates of a point. Let’s look at where this point-slope formula comes from. Find the Equation of a Line Given That You Know a Point on the Line And Its Slope The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line.
