A terminal point \((x,~y)\) lies strictly inside \(\text{Quadrant}~I\) on the unit circle. Use the diagram to determine the signs of \(\sin(θ)\), \(\cos(θ)\), and \(\tan(θ)\), and verify them from the signs of \(x\), \(y\), and \(y/x\).

Trig signs come directly from terminal-point coordinates rather than from a separate rule to memorize. Cosine follows the horizontal coordinate, sine follows the vertical coordinate, and tangent follows their quotient. Because the point lies strictly inside a quadrant, neither coordinate is zero, so the tangent sign is determined normally.
