Principles before formulas, with physiology examples throughout - kinematics and fluids to circuits, optics, and nuclear physics.
With the angle measured FROM THE HORIZONTAL: the horizontal (adjacent) component uses COSINE, Vx = V cos(θ); the vertical (opposite) component uses SINE, Vy = V sin(θ). If the angle is instead measured FROM THE VERTICAL, the two swap. Do not memorize a fixed rule; draw the triangle and ask whether the component you want is adjacent to the angle (cosine) or opposite it (sine). At small angles the horizontal piece dominates; near 90 degrees the vertical piece does.…
