Best books to learn Trigonometry, in order
Trigonometry is the bridge from geometry to calculus, and it's easy to learn as disconnected formulas. The order that sticks starts with angles and right triangles, then the unit circle that unifies everything, then the identities and applications that show up everywhere later. The unit circle is the hinge — meet it too late and the functions feel arbitrary. Triangles first, then the circle, then the identities.
