@top_maths_5m: The tangent of an angle, in the unit circle, is the segment between the extended radius and the vertical line at x = 1. • It grows very large as the angle approaches 90^\circ! Cotangent is represented using a horizontal line at y = 1, and similarly grows very large as the angle approaches 0^\circ. Visualizing them makes all the difference! #math #animation #tangent #trigonometry #fyp
