Hey everyone! So, I've got my SAT coming up real soon and I'm focusing on the Math section right now. I was kind of hoping I could find a list of all the formulas that I will need for the test. Does anyone know where I can get my hands on this?
Sure, let's break down the formulas you might need for the SAT Math section. There are several aspects of math you should be familiar with:
1. Basic Algebra: This includes basic formulas like the distributive, associative, and commutative laws, as well as understanding how to solve for x in equations, and the slope-intercept form (y=mx+b).
2. Advanced Algebra: This includes understanding the quadratic formula ([-b±√(b²-4ac)]/2a), and the properties of exponents (for instance, x^ax^b= x^(a+b)).
3. Geometry: You should be well familiar with the Pythagorean theorem (a²+b²=c² for the sides of a right triangle), the area of a circle (πr²) and a triangle (1/2bh), the circumference of a circle (2πr), and special right triangles (30-60-90 and 45-45-90 triangles).
4. Trigonometry: This includes trigonometric identities such as sin²(θ)+cos²(θ)=1, SIN = Opposite/Hypotenuse, COS = Adjacent/Hypotenuse, and TAN = Opposite/Adjacent.
5. Statistics: Dear familiar with mean (average), median (middle), mode (most frequent), and how to calculate standard deviation, probability, and range.
Remember, practicing with these formulas and understanding how to apply them in different circumstances will be extremely beneficial. So, practice extensively to get the most benefit!
Good luck with your preparation!
