Distance formula between a point and a line
This proof shows a formula for calculating the distance between a point and a line in the form of y = ax + b.
This proof shows a formula for calculating the distance between a point and a line in the form of y = ax + b.
This proofs shows how the famous Pythagorean theorem works: a^2 + b^2 = c^2
This proof shows that sine divided by cosine is tangent.
