Piecewise Functions - Limits and Continuity | Calculus

Teacherflix
56 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.

The Transatlantic Slave Trade: Crash Course Black American History #1

Teacherflix
11 Views · 2 years ago

Today we're learning about the Transatlantic Slave Trade, which brought millions of captive Africans to the Americas between the 16th and 19th centuries, with the largest number of people trafficked between 1700 and 1808. We'll look at the ships and crews that brought enslaved people across the ocean via what was known as the Middle Passage and explore the horrific conditions that these captives endured.

Hello Happy friends!
Are you ready to learn?

I’m Sarah, and today, we’re going to talk about our sight and optical illusions.

Do you know what an optical illusion is?
Human beings, are visual beings. That means, that we identify almost anything with our sight, It’s our most important sense.

The light entering our eyes, goes directly to our brain, through electrical signals, and this is where they are transformed into real images, which is what we really see.

Although, at times, our brain can trick us!
It make us see things, that aren’t really what we think they look like, and these are, optical illusions.

Today. We’re going to look at some of the top 5 most shocking optical illusions.
They are amazing!

Look at this image!
Do you think that the horizontal lines are straight and parallel to each other?
I don’t think so!
I think there’s even some that are curved!

But, if we get rid of the black squares…
We can verify that they are completely straight and parallel to each other.
It’s honestly mind-blowing!

Let’s take a look at the second optical illusion.
Which one of the middle circles do you think is bigger?
Mmm… I think its the left one.
But… They are exactly the same!

It’s incredible!
Let’s see the next one!
Look at this image.
What animal can you see here?
If you’ve seen a duck, you’re right!
But you could have also seen, a jumping rabbit! Look!

And now, look at this image
What does the square look like?
Is it like this? Or like this?
I’m sure it’s the curved one!
Let’s make sure!
Hmm… It’s actually not… Let’s see…
It’s the straight lined one! We’ve been tricked by our brains once again!

And now, to finish off, we’re going to see my favorite optical illusion.
How many animals can you see?
I can see an elephant, a horse, a dog, a cat, and a mouse!
Can you see any more?
Hmmm… Wait! I see a gorilla!

I love optical illusions! I find them so much fun!

Goodbye happy friends! See you next time!

I hope you’re always ready to learn!

Goodbye!

Lyrics:
We all come from a place
The entire human race
Depends upon our planet
Racing through outer space
And there are eight planets
That orbit around the sun
Come on, we’ll introduce you
And name them one by one:

Chorus
Mercury, Venus, Earth and Mars
Jupiter, Saturn
Uranus, Neptune

Mercury, Venus, Earth and Mars
Jupiter, Saturn
Uranus, Neptune

Mercury:
I’m Mercury, the smallest planet, you see
You humans could never live on me
My atmosphere’s too thin, and I orbit too fast
My days are long

Star:
About 60 earth days as a matter of fact

Venus:
I am Venus, my atmosphere’s super hot
I spin backwards in a way the earth does not
I’m closest to the earth in distance and size
I have no moons, I hope you can sympathize

Earth:
I’m earth, the planet that you’re on, ya know
I’m terrestrial, but covered in H20
I collide with things that I can’t avoid
But my atmosphere protects me from meteoroids

Mars:
I’m Mars and you can jump higher on me,
Because I have a third of earth’s gravity
I hear you plan to visit soon
I’ll be your first destination since the moon

Jupiter:
I’m Jupiter, with my 79 moon crew
Like Io and S/2003…

Moons:
J 2!

Jupiter:
Yea, you could say I have a pretty large girth
Here’s a storm twice the size of yo momma,
Earth

Moons:
Ohhh!

Saturn:
My name’s Saturn, check out my pretty rings
These rings are a few of my favorite things
I’m a giant made of hydrogen and helium
And please, stop hitting me with things

Uranus:
My name’s Uranus, and I’m an ice giant

Neptune:
That’s dope!

Uranus:
I was the first planet found with a telescope
I rotate backwards, and on my side
I smell like rotten eggs,
But that’s just the hydrogen sulfide

Neptune:
I’m Neptune, I’m the windiest planet around
I’ve got supersonic winds
That’s faster than sound
An ice giant with 14* moons
And a dark vortex that may go away soon

Pluto:
I’m Pluto, and I will not be forgotten!

Stage Manager:
Pluto, Pluto, Pluto, Pluto… beautiful, but, um… yea, we’ve been over this, and… you’re considered a dwarf planet these days, sooo…

Pluto:
Gurl, I’m the biggest object in the Kuiper Belt.

Mercury, Venus, Earth and Mars
Jupiter, Saturn
Uranus, Neptune

Jupiter:
Sing along, real strong, for the next tune

Mercury, Venus, Earth and Mars
Jupiter, Saturn
Uranus, Neptune

Pluto:
And, I guess, not Pluto
