When I first started I made the circle for the head. Then I made the eyes, followed by half the mouth, then hair, then the rest of the mouth, then nose. The thing that took most time was the hair because I used trig for that. Most of the things I did was guessed and check for the numbers to see if they will move, but over time I kind of knew sort of where they were, but still guessed and check to get them in the exact place. Some challenges were when I really did not know how to move the line so I just used a different line for it. Good moments were when the line went to the exact place I wanted it to be. Some strategies I used for the eyes was do one side, then copy and paste and put negative signs for the other side, because it is symmetrical and it will work. Same for the hair. Another challenge was Desmos only had like 6 colours so like, I didn’t know how to get more and when I tried mixing it, it didn’t work. So I had to do the eyes black instead of brown. This assignment helped me understand the { < x < } more, because it was used quite a lot while I was making it, and how trigonometry was pretty useful when doing this project.

Flag Pole Lab Math 10 2019

Flag Pole Lab

For the lab today in math, we had to find out the height of the flagpole. We first measured the height of the person from eye level. My partner was Ben and it was 151cm.

Later, we stood far away and measured the angle. He was holding the thingy and I had to see what angle it was at. It was hard because the string did not stay still, but I managed to see it and it was 44º.

After we measured the angle then we had to measure the distance from us to the flag pole. We used 2 things to measure it. A tape measurer, and the rolling thing. For the tape measurer we got 28ft 5 inches which was 8m 66cm. And from the other thing we got 8m 55cm so it was close.

And after some math we got like over 9m for the measurement of the flag pole.

Trigonometry can be used when you cannot measure with Pythagorus Theorem or when you can’t measure what ever it is, but as long as you have a side and an angle you can find anything.

Infinite Thoughts

What do you know about infinity?

It looks like ∞ and it is infinite.

What new things have you discovered?

There are different kinds of infinity.

How can you explain/makes sense of different sizes of infinity?

There are ones like 1, 2, 3, 4, 5, 6…

There are also ones that are like 1, 1.1, 1.2, 1.3… and stuff.

What are countable infinities? What are non countable infinities?

Countable is what you can count like 1, 2, 3, 4, 5, 6, 7, 8…

Non countable is like 1, 1.1, 1.01, 1.001, 1.0001, 1.00001… like stuff you can’t count.

What questions do you still have about infinity?

Is the universe infinite?

Is reality infinite?

Why is infinity?

Is anything infinite?

Why is it named infinity?
