TRIGNOMETRY BASIC KIT WORKING MODEL

In trigonometry, we often work with triangles and angles to solve various types of problems. Here are some basic concepts and techniques commonly used in trigonometry:

1. Trigonometric Functions:

• The primary trigonometric functions are sine (sin), cosine (cos), and tangent (tan).
• These functions relate the angles of a right triangle to the lengths of its sides.
• In a right triangle with an angle θ:
  • Sin(θ) = Opposite / Hypotenuse
  • Cos(θ) = Adjacent / Hypotenuse
  • Tan(θ) = Opposite / Adjacent

2. Pythagorean Theorem:

• The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
• �2=�2+�2c2=a2+b2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

3. Trigonometric Identities:

• Trigonometric identities are equations involving trigonometric functions that are true for all values of the variables.
• Some common trigonometric identities include:
  • Pythagorean identities: ���2(�)+���2(�)=1sin2(θ)+cos2(θ)=1 and ���2(�)+1=���2(�)tan2(θ)+1=sec2(θ)
  • Reciprocal identities: $csc(\theta )=1/sin(\theta )$, $sec(\theta )=1/cos(\theta )$, $cot(\theta )=1/tan(\theta )$
  • Quotient identities: $tan(\theta )=sin(\theta )/cos(\theta )$, $cot(\theta )=cos(\theta )/sin(\theta )$

4. Solving Right Triangles:

• Given a right triangle with known side lengths or angles, trigonometric functions can be used to find missing side lengths or angles.
• Use inverse trigonometric functions (sin⁻¹, cos⁻¹, tan⁻¹) to find angles given side lengths or ratios.

5. Applications:

• Trigonometry has many practical applications, such as in navigation, engineering, physics, and astronomy.
• It can be used to solve problems involving distances, heights, angles, and trajectories.

Trigonometry provides a powerful set of tools for solving problems involving triangles and angles, making it a fundamental subject in mathematics with wide-ranging applications.
