MARKING PERIOD I
Quadratics Quiz
GRADE- 50%
What i didn't do well on- In the recent quiz, we were assigned with graphing quadratic equations, a process that involved identifying several important features: the zeros, y-intercept, axis of symmetry (A.O.S.), and vertex. i realized I need to improve my skills, as I miscalculated components such as the the y-intercept in the vertex, and zeros, leading to an incorrect graph that did not accurately represent the equation. Furthermore, I also forgot to include the axis of symmetry, a vital element in understanding the properties of quadratic functions. To address these issues, I plan to practice more, especially since we weren’t allowed to use calculators, which made the task more difficult.
UNIT 1, SECTION 2 TEST
GRADE- 82%
What i did well at- In Unit 1, Section 2, we reviewed what we learned about understanding I have been studying polynomials, which includes understanding various quadratic equations, how to solve them, create equations, and graph them. I received an 82, which isn't the worst grade, but I want to improve my grasp of these concepts. I'm proud of my grade because it demonstrates that I have a basic understanding of the material. Polynomials are algebraic expressions that consist of variables and coefficients. One important concept I learned is how to find the zeros of a polynomial, which are the values that make the equation equal to zero when solving for X. I also understand the end behavior of graphs, analyzing them from right to left. Overall, this learning process has helped me identify areas where I need to improve, as well as what I already understand about polynomials.
MARKING PERIOD 2
GRADE-100%
What i did well at-During the Christmas break, our assignment involved completing a total of 36 challenges where we had to create different types of equations to collect all the stars. I chose this assignment because it required a significant amount of time and numerous calculations to ensure that I gathered each star. I learned a lot after working extensively with linear and quadratic equations, including how to cut out specific portions of a line and even how to create a circle. In the end, I was glad to have finished this assignment despite the challenges it presented.
GRADE- 45%
What i didn't do well on- In this transformation quiz, we are given a graph representing a specific point, referred to as f(x), and we need to analyze how the quadratic formula changes as it moves to the third quadrant and concaves down. This transformed function will be called g(x). Additionally, we need to determine what the equation would be if it started from the origin (0,0) while documenting the transformations for each change. Overall, I had a basic understanding of what I needed to do, but I struggled to write everything clearly on paper. One thing I could have done better is to ask for clarification on how and why I got some questions wrong. Although I thought I received a good grade, I wanted to understand the reasoning behind my score. Unfortunately, with other classes and assignments, I didn't have time to address my concerns about my grade.
MARKING PERIOD 3
GRADE- 70%
LOGARITHMS QUIZ
What i didn't do well on- This quiz was designed with care to challenge our knowledge of logarithms and how they are applied to calculate squares and simplify mathematical expressions. Although I usually had an elementary understanding of the concepts—knowing, for example, that division of squares is subtraction and multiplication is addition—there were some areas where I might have done better. In the first question, for instance, I omitted the logarithmic function logm - logn from my answer. By doing so, this mistake was pivotal because it revealed a gap in my ability to integrate the relevant mathematical principles in that context. By leaving out this significant element, my answer was not only lacking but also far too shallow and incorrect to properly solve the question. Reflecting on my performance, I acknowledge that while I have a solid conceptual understanding of logarithmic functions and their application, rigid control over detail is essential. Small oversights like the one I committed have a strong impact on the clarity and comprehensiveness of my answers. Being more meticulous and precise in my response, I feel that my results could see considerable improvement in future tests.
GRADE- 95%
EXPONENTS TEST
What i did will on- I performed well on the recent test focused on exponential functions and graphing. The exam required evaluating and simplifying equations, and I excelled in graphing and solving word problems. The formula (a * b^x) is key for exponential functions, where 'a' is the initial value, 'b' is the growth or decay factor, and 'x' is the exponent. If 'b' is greater than 1, it indicates growth; if it's between 0 and 1, it indicates decay. I learned important rules about exponents: when multiplying with the same base, add the exponents; when dividing, subtract them. A negative exponent represents the reciprocal of the base raised to the positive exponent. I also found that square roots can be converted into exponential forms, which helps in simplifying answers. Overall, I grasped most concepts, preparing me for future math topics.
MARKING PERIOD 4
GRADE- 65
The assignment emphasizes the importance of understanding the fundamental concepts of the unit circle rather than simply memorizing facts. The unit circle, which has a radius of one unit and is centered at the origin (0,0) on a coordinate plane, is crucial for enhancing our comprehension of pre-calculus. It serves as a valuable tool in trigonometry, illustrating the relationships between angles and the sine, cosine, and tangent values. Reflecting on my experiences with the unit circle, I recognize that I could have improved my understanding by studying more diligently, especially given the opportunities provided to enhance my grasp of how these functions behave. Overall, I have identified areas for improvement in my understanding of this concept.
GRADE- 90%
In this quiz, we explored trigonometric functions such as sine, cosine, and tangent, which are defined using the unit circle—a circle with a radius of 1. The unit circle helps establish relationships between angles and the coordinates of points on the circle. For any angle θ, we can identify its terminal side on the unit circle, forming a right triangle with the x-axis. The x-coordinate of the intersection point is cos(θ), while the y-coordinate is sin(θ).
For example, when we draw a 30-degree angle in standard position, with its vertex at the origin and its initial side on the positive x-axis, the terminal side intersects the unit circle at the point (√3/2, 1/2). This means that cos(30°) is √3/2 and sin(30°) is 1/2. Additionally, we can determine the tangent of 30 degrees using the ratio of sine to cosine: tan(30°) = sin(30°)/cos(30°) = (1/2) / (√3/2) = 1/√3, which simplifies to √3/3.
Overall, the quiz served as a useful reminder of how the unit circle is applied in trigonometry and also something im glad i had a good grade on.
