TRIGONOMETRY COMPOUND ANGLES PART 2

[@ms-tj1ms]

Excellent teaching sir...

[@mohitkrishna7799]

Trigonometry compound angles are explored, focusing on formulas for sine, cosine, and tangent. Key results include relationships for tan(a + b) and tan(a - b), leading to the calculation of tan(A + B + C). Practical examples like sin 75° and cos 75° are demonstrated using angle addition formulas. Key moments: 00:32 The video explains the formulas for cosine and tangent in relation to angles A and B. It demonstrates how to derive these formulas using fundamental trigonometric identities and relationships. -The relationship between sine and cosine is fundamental in trigonometry, helping to simplify expressions involving angles. This is illustrated through the manipulation of cosine squares and sine squares. -The importance of knowing trigonometric identities cannot be overstated, as they simplify complex equations. These identities are essential for further studies in mathematics and physics. -Deriving the formulas for tangent addition and subtraction involves understanding how to combine angles effectively. This leads to practical applications in solving trigonometric problems. 03:01 The video explains how to calculate the tangent of the sum of angles A, B, and C using a specific formula. It emphasizes the importance of understanding the relationships between tangent values for various angle combinations. -The formula for tan(A + B) is derived using tangent identities to simplify calculations involving angles A and B. This approach is crucial for solving complex trigonometric problems. -Understanding the addition formula for tangent helps in solving real-world problems involving angles in physics and engineering. This knowledge can be applied to various fields. -The video also discusses how to extend the tangent addition formula for three angles, which is essential for more advanced trigonometric applications. This is critical in higher mathematics. 07:31 The formula for the sum of tangents in a triangle can be expressed simply and memorably. It relates the sum and product of tangents of angles A, B, and C. -The formula can be remembered as Sigma tan a - P tan a by 1 - Sigma tan a tan B. This mnemonic aids in quick recall during problem-solving. -Understanding the relationship between the sum of tangents and their products is crucial. This can help in simplifying complex trigonometric calculations. -The significance of the angles A, B, and C in determining the overall properties of the triangle is emphasized. Their relationships are fundamental in trigonometry. 08:10 The video explains how to calculate trigonometric functions for specific angles using the sine and cosine addition formulas. Understanding these calculations is essential for competitive entrance examinations. -The relationship between tangent and the sine and cosine functions is highlighted, showcasing how they interconnect. Mastery of these relationships is vital for solving trigonometric problems. -The sine of 75 degrees can be derived from the angles 45 and 30 degrees using the sine addition formula. This method simplifies the calculation significantly. -To find the cosine of 75 degrees, the cosine addition formula involving 45 and 30 degrees is utilized. This formula helps in accurately computing the cosine value. Generated by sider.ai
