Key Concepts

Vector Decomposition

Vector decomposition is the process of breaking down a vector into its horizontal and vertical components. This is useful in physics and engineering to analyze the effects of forces and motions along perpendicular directions, allowing complex vector situations to be simplified using basic arithmetic and trigonometry.

Right Triangle Trigonometry

Right triangle trigonometry involves using the sine and cosine functions, which relate the angles of a triangle to the ratios of its sides. When a vector is oriented at an angle from the horizontal, its horizontal component can be calculated with the cosine function and its vertical component with the sine function, forming the basis for resolving the vector.

Rounding

Rounding is the process of adjusting numerical values to a specified level of precision, such as to the nearest hundredth. This practice is important in applied mathematics and engineering to ensure that answers are both simplified and appropriately accurate for practical use.
