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…

The video we watched made me want to learn more about measurements and it was very interesting. It was cool to see what people…
