• The tangent ratio (tan) is calculated as the length of the side opposite the given angle divided by the length of the side adjacent to the angle.
• The sine ratio (sin) is calculated as the length of the side opposite the given angle divided by the hypotenuse.
• Sine, cosine, and tangent are trigonometric ratios used in right-angled triangles to relate the angles to the sides.
• In trigonometry, there are six basic functions that can be used to find unknown angles or sides:
• Sine function (sin): The sine of an angle is equal to the length of the side opposite the angle divided by the length of the hypotenuse.
• Cosine function (cos): The cosine of an angle is equal to the length of the side adjacent to the angle divided by the length of the hypotenuse.
• The cosine ratio (cos) is calculated as the length of the side adjacent to the given angle divided by the hypotenuse.
