What are the top 5 formulas in math?
Algebra
Completing the square: x2+bx+c=(x+b2)2−b24+c.Quadratic formula: the roots of ax2+bx+c are −b±√b2−4ac2a.Circle: circumference=2πr, area=πr2.Sphere: vol=4πr3/3, surface area=4πr2.Cylinder: vol=πr2h, lateral area=2πrh, total surface area=2πrh+2πr2.
Do you have to memorize formulas for the ACT?
Here’s the thing about the ACT math section: even with all the ACT math test prep you did, the ACT doesn’t give you a cheat sheet with all the math formulas written down on them. Therefore, it’s up to you to learn, memorize and understand them.

Does ACT give formula sheet?
The ACT does not provide a formula sheet for the Math section, so you’ll need to know a few key formulas by heart. It’s important to understand these formulas because the ACT math test is pretty straightforward; often knowledge of these key formulas can help you solve problems faster and more accurately.
What is famous math formula?
E=mc^2. For our first, we’ll take perhaps the most famous equation of all. Albert Einstein’s 1905 equation relating mass and energy is both elegant and superficially counterintuitive. It says that energy is equal to the mass of an object in its rest frame multiplied by the speed of light squared.
