Coming to an end of Pre-Calc 11, the top 5 things I learned during this class is factoring, analyzing quadratic function in the form of , understanding the different laws of trigonometry, non-permissible values and rational expressions. Firstly, factoring. Throughout the units of pre-calc 11, one thing that always came up was factoring. Whether it […]

Week 17 – Pre-Calc 11 – Sine law
Key Vocabs: Sine law: the relationship between the sides and angles of a non-right triangle This week for our trigonometry unit, we began learning about the sine and cosine law. I’ll be talking about the sine law it’s more interesting than cosine law to me. The sine law can be used in any triangle to […]
Week 16 – Pre-Calc 11 – Special Triangles
Key Vocabs: Special triangles: 45-45-90 & 30-60-90. These triangles are called special triangles because the ratio of the triangles can easily be memorized, which can help us when we’re solving trigonometry problems without any use of our calculators. Quadrant: Can be any of the 4 areas made when we divide a plane by an and […]
Week 15 – Pre-Calc 11 – Intro to Trigonometry
Key Vocabs: Pythagorean theorem: The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides () Hypotenuse: The longest side of a right triangle Primary trigonometric ratios: Sine (sin), Cosine (cos) and Tangent (tan) Moving on from rational expressions and equations, our final unit for […]
Week 14 – Pre-Calc 11 – Solving Rational Equations
Key Vocabs: Non-permissible values: Values of the variable(s) that make the denominator of a rational expression equal to zero Monomial: A polynomial with 1 term (ex. ) Binomial: A polynomial with 2 terms (ex. ) Trinomial: A polynomial with 3 terms (ex. ) Moving on from addition, subtraction, multiplication, and dividing rational expressions, we began […]
Week 13 – Pre-Calc 11 – Adding and Subtracting Rational Expressions
Key Vocabs: Denominator: the bottom number in a fraction that shows the number of equal parts an item is divided into Numerator: the top number in a fraction that shows the number being divided by the denominator Binomial: A polynomial with 2 terms (ex. ) Trinomial: A polynomial with 3 terms (ex. ) With multiplying […]
Week 12 – Pre-Calc 11 – Simplifying Rational Expressions
Key Vocabs: Rational Expressions: is an algebraic expression that can be written as the quotient of two polynomials Non-permissible values: Values of the variable(s) that make the denominator of a rational expression equal to zero Denominator: the bottom number in a fraction that shows the number of equal parts an item is divided into For […]
Week 11 – Pre-Calc 11 – Forms of Quadratics
Key Vocabs: Standard/Vertex form: General Form: Factored Form: r1) r2) Parabola: The graph of every quadratic function is a curve which is called a parabola Maximum: Minimum: This week, our class had our unit 4 test along with an continuation of the rest of the unit. During the test, I realized most of the questions […]
Week 10 – Pre-Calc 11 – Equivalent forms of the quadratic functions
Key Vocabs: General form: Standard/Vertex form: Parabola: The graph of every quadratic function is a curve which is called a parabola Axis of symmetry: A straight line that divides through the parabola into two identical parts For our 10th week of Pre-Calc 11, our class began to notice some clues that could lead us into […]
Week 9 – Pre-Calc 11 – Vertex
Key Vocabs: Parent function (of a parabola): Vertex: Is the highest or lowest point of a parabola Parabola: The graph of every quadratic function is a curve which is called a parabola Minimum point: Maximum point: In our 9th week of Pre-Calc 11, our class continued from last week’s lesson on properties of a […]
