This week was a very short week so we didn’t go over too much stuff but we still learned a couple of things. We learned how to graph quadratic and linear inequalities, to graph a quadratic inequality you would need to find the y-intercept and the vertex and use those numbers to graph it and find the solutions and where it’s going to be shaded in the graph. So, for example, . The y-intercept would be 8 and you can tell it opens up since the is positive, and the pattern is 1, 3, 5 because the leading coefficient is 1. So now you would factor into , and from that, you can find the vertex which would be -4 and -2 which would be your x-intercepts. To find the vertex you would and you vertex would be -3 and by plugging it into your equation you could find the minimum point connected to the vertex and graph it.

This week in math we started a new unit which is trigonometry, this was a nice little throwback to grade 10 math but in grade 11 trig its a little different. In grade 11 trig there are way more things to learn and the simplicity of SOH CAH TOA won’t cut it for grade 11 […]
