Piecewise Functions - Limits and Continuity | Calculus Teacherflix 87 Views • 2 years ago

This calculus review video tutorial explains how to evaluate limits using piecewise functions and how to make a piecewise function continuous by finding the constant c to make the two parts equal. This video on limits and continuity contains plenty of examples and practice problems for you to work. It discusses how to find if the limit exist by analyzing the one sided limits such as finding the limit as x approaches a number from the left and from the right.

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

The Bicycle: Great inventions that changed history.

Hello friends! Welcome to a new HAppy Learning Video! Today, in our section great inventions of history, we’re going to get to know… the bicycle.

The bicycle is one of the most fun means of transport there is! Also, it is very ecological, and very healthy! Since when we ride a bicycle, we do physical exercise!
But… do you know who, and when the bicycle was invented? No? Well, let’s find out!

The truth is, that alike many other inventions, the bicycle was invented in various phases and it was various people who intervened in its evolution until reaching the bicycle we know today!

Here you can see the first bicycle in history! It was invented by Karl Drais in 1817 but, it doesn’t look a lot like contemporary bikes, it didn’t have pedals and you had to push it with feet on the ground.

In 1861, the Frenchman Ernest Michaux thought of putting pedals on the front wheel, but because it didn’t balance correctly, people fell off and his idea didn’t succeed. But it was useful so in 1873, James Starley, an English inventor, would manufacture a bicycle with the front wheel a lot bigger than the back one. Although the falls from so high up were dangerous, he made it easier to drive them, so in 1873, Thomas Steven commenced the first trip around the world. He took three years to finish it.

In 1885, John Kemp Starley, James Starley’s nephew invented a safe bicycle. Because it had breaks, and was a lot lower, falls were less frequent and less dangerous. Exactly, it was more secure… he had created a contemporary bicycle. From this moment on, the bicycle became famous throughout the whole world. And it started to be used for Cirque shows, to travel or just to do sports. But… the bicycle’s history hasn’t ended, there are still new bikes being invented, like mountain bikes, race bikes, electric or some which won’t move no matter how fast you pedal, like at the gym… There are a lot of curious bicycles, like all of these… It’s clear that the bicycle is an invention which runs smoothly! So everyone let’s ride a bike!
