Single-variable equations (e.g., x=5) graph as vertical lines. Sliders: Create by typing a=1. Use to visually solve for constants. Avoid using 0 or 1 as test values. Functions: Type f(x)=... to define. Then use f(2) to evaluate or f(x+2) for transformations. Tables & Points: Click "+" and "Table" to input points. Use "Zoom Fit" to see all points. Regression: The most powerful feature. Use the ~ symbol (tilde). For regression, replace the variable with a constant (e.g., x becomes x1). Change = to ~. Finding Constants: If solving for a letter like a or b, you must tell Desmos it's constant for all x. Set the variable to a list of numbers. Systems of Equations: Use brackets. Put all left sides in one list and all right sides in another, separated by ~. Example: [2x1+3y1, x1-y1] ~ [12, 4]. Table Regression (anytime the question gives you points): 1) Input points into a table, 2) Type the equation that goes through the points, and 3) Change it to regression format. Number of Solutions: Graph the left and right sides of the equation as separate lines. The number of intersections is the number of solutions. Circle Questions: Graph the circle equation. Use the "distance" and "midpoint" functions between the max and min points to find the radius and center. Equivalent Expressions: Type y= before each answer choice. The one that graphs identically to the original expression is correct. To check if expressions are factors of each other, see if they have the same x-intercept. Useful Functions: mean(), median(), stdev(), distance(point1, point2), midpoint(point1, point2) Why watch? If this is your first view—hi, I’m James 👋 I've personally scored a 1570 on the Digital SAT (770 English, 800 Math) and have spent thousands of hours split-testing strategies, analyzing data, and building a system that helps students reliably break into the 1500+ range. Today there are a lot of SAT tutors online, but I’ve noticed none of the strategies they share even compare to the ones I've discovered in terms of effectiveness. So this channel is my way of transforming the SAT industry. Hopefully I can help you improve your SAT score, and in doing so, open doors that shape the rest of your life 🙏 Like, subscribe, and leave me a comment if you have a specific request! Thanks.
