10 Questions
What is the definition of environment?
Environment can be defined as One’s surroundings which include everything around the organism, i.e. Abiotic (Non-living) and Biotic (Living) environment.
What are the two components of environment?
The two components of environment are abiotic (non-living) component and biotic (living) component.
Give an example of a biotic component of environment.
An example of a biotic component of environment is flora (plants) and fauna (animals).
Give an example of an abiotic component of environment.
An example of an abiotic component of environment is soil.
What are the abiotic components of the environment of a carp fish in a pond?
The abiotic components of the environment of a carp fish in a pond are light, temperature, and water in which nutrients, oxygen, other gases, and organic matter are dissolved.
What are the six trigonometric functions?
The six trigonometric functions are sine, cosine, tangent, cotangent, secant, and cosecant.
Define the trigonometric ratios of an angle in a right triangle.
The trigonometric ratios of an angle in a right triangle are defined as follows: \n$\sin A = \frac{P},{H}$, $\cos A = \frac{B},{H}$, $\tan A = \frac{B},{P}$, $\csc A = \frac{H},{P}$, $\sec A = \frac{H},{B}$, $\cot A = \frac{B},{P}$.
What is the relationship between the angles and sides of a triangle in trigonometry?
Trigonometry functions define the relationship between the angles and sides of a triangle.
How many trigonometric ratios are there?
There are six trigonometric ratios.
Can the values of the trigonometric ratios of an angle vary with the lengths of the sides?
No, the values of the trigonometric ratios of an angle do not vary with the lengths of the sides.
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.
