I'm testing Brainly's community and what percentage of people actually understand the majority of material here and if they want to actually help others.

To get these 100 points, follow the following steps. If you do not follow these steps and just write in an answer, your answer will be deleted.
1) What is sin^-1, cos^-1, and tan^-1 also called? What are these inverse trigonometric ratios used for (i.e. used for finding side lengths from another side length and an angle).
2) What are the main 3 calculus tools?
3) Prove that the slope of Standard Form (Linear Equations) is -A/B.
4) What is y = 1/x called? i.e. y = x^2 is called a parabola.
