Let us practise and revise what we learned about trigonometry. Trigonometry studies relationships between angles and sides of triangles, par
Core concept
In a right triangle, sine (sin) is the ratio of the opposite side to the hypotenuse, relative to a given angle.
How it works
Cosine (cos) is the ratio of the adjacent side to the hypotenuse, while tangent (tan) is the ratio of opposite to adjacent sides.
Why it matters
These trigonometric ratios remain constant for a given angle, regardless of the triangle's size, making them powerful tools for calculations.
Key detail
Trigonometry has practical applications in fields like architecture, navigation, and physics, especially for calculating heights and distances.
