Awesome Math Tricks: Vertex Form, Difference of Cubes, and Sines and Cosines






Page 2: Advanced Algebraic Forms and Functions
This page delves into more complex algebraic forms including polynomial functions, difference of cubes, and exponential expressions.
Definition: The difference of cubes formula states that a³-b³ =
Example: The equation of a circle in standard form is ² + ² = r², where (h,k) is the center and r is the radius
Highlight: Polynomial functions can be written in factored form as f(x) = a(x−p)(x−q)(x−r) where p, q, and r are the roots
Vocabulary: A fractional exponent can be converted to a radical form, where a^ = ⁿ√a

Page 3: Exponential and Logarithmic Functions
This page covers exponential growth, decay, and logarithmic functions, with applications in compound interest and half-life calculations.
Definition: Compound interest formula: A = Pⁿ, where A is final amount, P is principal, r is interest rate, and n is number of periods
Example: For continuous compound interest, the formula A = Pe^(rt) is used, where e is Euler's number
Highlight: The half-life formula N(t) = N₀(1/2)^ is crucial in radioactive decay calculations
Vocabulary: Asymptotes are lines that a curve approaches but never touches, defined by x = h and y = k in hyperbolic functions

Page 4: Trigonometric Functions and Probability
This page explores trigonometric relationships and probability calculations, including the laws of sines and cosines.
Definition: The law of cosines states that a² = b² + c² - 2bc cos(A) for any triangle
Example: The area of any triangle can be calculated using A = de sin(f), where d and e are sides and f is the included angle
Highlight: Permutations calculate arrangements where order matters
Vocabulary: The law of sines relates side lengths to angles: sin(A)/a = sin(B)/b = sin(C)/c

Page 5: Advanced Mathematical Concepts
This page concludes with advanced mathematical concepts and specialized formulas for probability and trigonometric calculations.
Definition: The probability formula for multiple selections involves combinations and specific conditions
Example: Vertical shifts in trigonometric functions are represented by adding or subtracting constants
Highlight: The tangent function V = tan(θ) relates to the ratio of sine and cosine
Vocabulary: Probability calculations often involve combinations for selecting items where order doesn't matter

Page 1: Essential Algebraic Formulas
This page introduces fundamental algebraic equations and formulas essential for mathematical problem-solving. The content focuses on various forms of linear and quadratic equations.
Definition: The quadratic formula is used to find the roots of any quadratic equation: x = /2a
Example: To find the axis of symmetry of a parabola, use the formula -b/2a
Highlight: The vertex form of a quadratic equation, f(x) = a(bx – h) + k, is particularly useful for graphing parabolas and finding maximum/minimum points
Vocabulary: Slope-intercept form represents a linear equation where 'm' is the slope and 'b' is the y-intercept

Students love us — and so will you.
The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.
This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.
Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
