What formulas should I need to know for SAT?

Like not the one’s that are already provided. So could anyone tell me what equations I need to memorize (for example should I know the quadratic equation? Etc.

The formula for slope, distance, midpoint, quadratics, and circles. Additionally, you should know how to complete the square (maybe), solve for angles/sides of triangles, convert units.

Do you mean slope distance and slope midpoint?

@GMKoon do you mean slope midpoint slope distance formulas?

Yes. You should also memorize the table they give you at the beginning of the test (area of circle, etc)

@GMKoon is it possible for you to show me what the formulas look like?

@GMKoon yes please that should help

@dodgerman711 Again, look at a practice test (which is written in the exact same format) for a formula sheet and other notes.

Also for quadratics: three forms (standard, vertex, x-intercept), equation of the axis of symmetry/x-coordinate of the vertex, the formula for the discriminant. I saw one official practice problem that required the quadratic equation.
Equation of a circle in center and standard forms.
Compound interest/population growth formula.
