    Mathematics

    What is trigonometry?

    Trigonometry relates the angles and sides of right triangles through sine, cosine and tangent, with applications to heights and distances.

    Why it matters

    It is a high-scoring Class 10 chapter and the standard tool for indirect measurement.

    Key concepts you will practise

    • Trigonometric ratios in a right triangle
    • Values at 0°, 30°, 45°, 60° and 90°
    • Fundamental identities such as sin²θ + cos²θ = 1
    • Heights and distances with angles of elevation and depression

    Tips that save marks

    • Draw and label the triangle before choosing a ratio.
    • SOH-CAH-TOA still picks the right ratio faster than anything else.

    Frequently asked questions

    What is the angle of elevation?

    The angle between the horizontal and the line of sight to an object above the observer.

    What is tan θ in terms of sin and cos?

    tan θ = sin θ / cos θ, undefined wherever cos θ = 0.
