Solving Quadratic Equations
Quadratic equations are equations written in the form of "ax2 + bx + c = 0". They generally have two solutions and produce a curve when graphed. This video explains how to solve quadratic equations by using factoring.
Trigonometric Functions
Trigonometric (triangle-measuring) functions relate one non-right angle of a right triangle to the ratio of the lengths of any two sides of the triangle, or vice versa. This video explains three of the most common trig functions: sine, cosine, and tangent.
Law of Sines
This video explains the Law of Sines.
The Law of Sines says that:
When we divide side a by the sine of angle A
it is equal to side b divided by the sine of angle B,
and also equal to side c divided by the sine of angle C.
This is useful for solving missing angles and sides in triangles.
