Study Notes

Environment

Environment is the surroundings in which living organisms exist.
Environment consists of two components: biotic and abiotic.
Biotic components of environment: living things, such as plants, animals, and microorganisms. Example: fish in a pond.
Abiotic components of environment: non-living things, such as light, temperature, water, and soil. Example: water in a pond.

Abiotic components: water, light, temperature, oxygen, and nutrients.

Trigonometry

Trigonometric ratios of an angle in a right triangle: ratios of the lengths of the sides of the triangle.
Relationship between the angles and sides of a triangle in trigonometry: trigonometric ratios are used to describe the relationships between the angles and sides of a triangle.
There are six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent.
The values of the trigonometric ratios of an angle do not vary with the lengths of the sides of the triangle.
