Math and Philosophy

We have been given a question from our Math teacher, “Is there absolute truth in mathematics?” Our group had a discussion and we all had different opinions 🙂

Why is… different? Using Algebra Tiles:// = To find the answer , I used algebra tiles. If you look at the image the to two long green tile represents . So x would make . A with the yellow tile which represents +1, would still be , because they are…

What I know about Sine, Cosine, and Tangent so far…

What is Sine, Cosine, and Tangent? They are 3 fundamental ratios of trigonometry. Each of these is a ratio of two sides of a right triangle. I know so far that: sine= opposite/hypotenuse. cos= adjacent/hypotenuse tan=opposite/adjacent Using sine, cosine, and tangent, we can find the ratio of the triangle If we do the inverse, than…

Garibaldi Lake

In class today, we were told to find the volume of the Garibaldi Lake and what would happen if the barrier faulted, how much water would escape and what kind of power is the escaping water equivalent to. We already knew the information of the surface area, the average depth, and the maximum depth of…

Measurement Reflection

October 5th, 2016: In class, we discussed about how we can measure objects without using rulers. It was very interesting to see many different ways that we can measure an object. The video we watched made me want to learn more about measurements and it was very interesting. It was cool to see what people…

The Graphs of Exponential Functions

Today in class, we got into a group of 3 and we were told to make a graph an exponential equation. Each group had a different exponent base. We were told to use a table of values with x values from -10 to 10 and find the y values and the plot the points. We…

Exponents: Introduction

Today in Math class, we reviewed exponents.

Math 10 Honours: Irrational Number

Irrational Number: e This number was discovered in 1618 by John Napier. We use e in problems that involves growth or decay, which also includes compound interest. We also use e in problems like the statistical “bell curve,” the shape of a hanging cable, some problems that involves probability, counting problems, and even when we learn…
