This week, I learned all about functions and how to put input values through them! Here’s how: Example 1: f(x) = 3x + 2 (Evaluate f(4)) Basically what this means is that we are using the function 3x + 2 and x = 2! f(x) is the value we are getting using this function! We can […]
This week, I learned how to discover the Domain and Range of a Graph! Here’s how: Example 1: First, to find the Domain of this graph, the domain is basically the input values of the graph! We need to look at the coordinates and find the values! Once we find the Values we write […]
This week I learned all about factoring polynomials! Here’s how: Example: Factor a simple trinomial ()! Step 1: First, imagine we are going to split the into two! We should start off with this: ( )( ) Step 2: Inside the blank spaces in the brackets, there should be a number! To find […]
Today I learned how to completely factor Polynomials! Here’s how: EXAMPLE: Factor Completely: STEP 1: Factor the polynomial! First we can factor the question already! Since we already have have ! Because we have to square the number when we factor it, we put down ! Here’s what it should look like: ( )( ) […]
Today I will teach you how to solve a Sphere and a Cone! Example 1: Solve the Sphere with the diameter of 10! First thing we need to know is the formulas! SA Sphere = 4πr V Sphere = 4/3 πr This is simple: To find the surface area we just need πr times 4! The radius is […]
This week, I learned how to use a new method to use the distributive property called (FOIL)! Here’s how: First – Multiply the first term in each set of parentheses Outer – Multiply the outer term in each set of parentheses Inner – Multiply the inner term in each set of parentheses Last – Multiply […]
This week I learned all about converting between Units! Here’s how: Example: Convert 1500 cm to ft! First, we need to convert 1500 cm to a much higher unit! Let’s do meters. This part is super easy, all we have to do is divide 1500 by 100: The answer is 15 meters! Next we need to […]
This week, I learned how to use a calculator to calculate missing angles and side lengths on a triangle! Example: Solve the right triangle! Using a calculator, we can find this angle! First, find the missing side length! We can use the pythagorean theorem to find this: The Value Rounds to 9.3! Next we will […]
Example 1: Exponents! Example 2: Fractions! Example 3: Exponents and Fractions! Example 4: Trig!
Video Demonstration This method is called the “Constellation” Method and this is similar to the “Tree” Method. However you make it look like a constellation so that way the space is much more organized. You can also get the LCM using the “Constellation” Method!
