Pythagorean theorem proofs Video transcript This triangle that we have right over here is a right triangle. And it's a right triangle because it has a 90 degree angle, or has a right angle in it. Now, we call the longest side of a right triangle, we call that side, and you could either view it as the longest side of the right triangle or the side opposite the 90 degree angle, it is called a hypotenuse.
Contact Instant Hacking This is a short introduction to the art of programming, with examples written in the programming language Python.
If you already know how to program, but want a short intro to Python, you may want to check out my article Instant Python.
To get the examples working properly, write the programs in a text file and then run that with the interpreter; do not try to run them directly in the interactive interpreter — not all of them will work. Check the documentation or send an email to help python. The Environment To program in Python, you must have an interpreter installed.
It exists for most platforms including Macintosh, Unix and Windows. More information about this can be found on the Python web site. You also should have a text editor like emacs, notepad or something similar. Programming a computer means giving it a set of instructions telling it what to do.
A computer program in many ways resembles recipes, like the ones we use for cooking. In jar with tight-fitting lid, combine all marinade ingredients; shake well. Place SPAM strips in plastic bag. Pour marinade over SPAM. Seal bag; marinate 30 minutes in refrigerator.
Remove SPAM from bag; reserve 2 tablespoons marinade. Heat reserved marinade in large skillet. Add SPAM, onion, and green pepper. Cook 3 to 4 minutes or until SPAM is heated. Line 4 individual salad plates with lettuce.
Spoon hot salad mixture over lettuce. Garnish with tomato halves. So what do we have to do to make this more computer-friendly? Well — basically two things. We have to 1 talk in a way that the computer can understand, and 2 talk about things that it can do something with.
In Python, this is quite simple: It tells the computer what to do: What if we would want it to do more stuff? And not really very interesting… We want to be able to do something with the ingredients, just like in the spam salad. Well — what ingredients do we have? For one thing, we have strings of text, like "Hello, world!
Say we wanted the computer to calculate the area of a rectangle for us. Then we could give it the following little recipe: The Area of a Rectangle Ingredients: But how does it work?
First of all, the lines beginning with are called comments and are actually ignored by the computer.§ Grade 6, Adopted (a) Introduction. (1) The desire to achieve educational excellence is the driving force behind the Texas essential knowledge and skills for mathematics, guided by the college and career readiness standards.
Port Manteaux churns out silly new words when you feed it an idea or two. Enter a word (or two) above and you'll get back a bunch of portmanteaux created by jamming together words that are conceptually related to your inputs.. For example, enter "giraffe" and you'll get .
Sal explains what it means for triangles to be similar, and how this follows from the definition of similarity.
