Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles.

• Trigonometry is used to calculate unknown angles or sides of triangles.

• It is also used in fields such as physics, engineering, and navigation.

• Trigonometric functions like sine, cosine, and tangent are fundamental in trigonometry.

• Trigonometry can be applied to solve real-world problems involving distances,...read more

Sin, cos, and tan are trigonometric functions used to relate the angles of a right triangle to the lengths of its sides.

• Sin (sine) is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

• Cos (cosine) is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.

• Tan (tangent) is the ratio of the length of the side opposite the angle to the length of the si...read more

Number system is a way of representing numbers using a set of symbols or digits.

• Number system is used to count, measure, and perform calculations.

• Common number systems include decimal, binary, octal, and hexadecimal.

• Each number system has a base or radix, which determines the number of unique digits it uses.

• For example, decimal system has a base of 10 and uses digits 0-9.

• Binary system has a base of 2 and uses digits 0 ...read more

Illustrate the concept of inheritance in object-oriented programming using a sample problem.

• Inheritance is a mechanism in OOP where a new class is derived from an existing class.

• The new class inherits all the properties and methods of the existing class.

• Example: A class Animal can be inherited by classes like Dog, Cat, etc.

• The derived class can add new properties and methods or override the existing ones.
