Digital SAT Math: Exploiting Desmos to save a LOT of time! :D
Digital SAT Math: Exploiting Desmos to save a LOT of time! :D
The dSAT has Desmos built-in, and it helped me get a perfect SAT Math score.
Desmos can do insane stuff quickly and easily - it almost feels like cheating when you know what it can do :3
After an intro to Desmos & graphing, and its integration in the dSAT app, we'll cover using Desmos to solve dSAT questions that need you to:
- Determine the equation of a line or parabola given a set of points (regression)
- Evaluate functions
- Solve an equation for a variable
- Solve systems of linear equations, inequalities, or quadratics
- Find the zeros of a quadratic/polynomial equation
- Answer exponential growth/decay questions
- Solve scatterplot & lines of best-fit questions
- Find the midpoint or distance between 2 points without the formulae
- Find the mean or median of a set of numbers
- Convert decimal numbers to fractions
- Easily solve percentage questions
- Find the slope & intercepts of any line
I'll also share practice problems for you to solve using Desmos and discuss.
Don't worry if you've never used Desmos before - I'll cover every ground. And if you're already a Desmos geek, I'm still certain you'll still learn something useful here :)
