What was challenging?
Problem #4 was very difficult at first glance because I wasn't exactly sure of the rules for 30-60-90 triangles. I struggled a lot with this problem, because it didn't give any of the lengths, yet we had to find what the base length was, only using the area. From there I looked at the angles. Along with the 90 degree angle, there was one labeled 60, meaning that must have some sort of significance. It turned out to be a 30-60-90 triangle, which has a specific equation for each side. The hypotenuse is h, the long leg is 1/2h times the square root of 3 and the short leg is 1/2h I found out this from this link: http://www.regentsprep.org/regents/math/algtrig/att2/ltri30.htm |

The most difficult problem was #12. Not only did it take multiple steps, but it also required neat work and a careful process because any small mistake can affect the entire problem. Process of elimination could not be used on this problem either, because it wasn't a multiple choice answer. I had to redo the problem about 4 times, which is why I did it on the white board with Phil. One specific mistake I made was forgetting to distribute the exponent to the whole equation, squaring all the components, not just the one next to the exponent. I learned from the mistake to complete the challenging problem. |
