The Trigonometric ratios table helps you to find the values of trigonometric standard angles 0°, 30°, 45°, 60° and 90°. The values of the angle are important for solving various trignometry problems. In mathematics, the trignometric functions relates the angles of a triangle to the len...
$\begingroup$ Even with this picture, you could use the area inclusion principle and argue that area of triangle OPQ < Area of sector OPQ < Area of triangle OPS. This translates into $\sin \theta < \theta < \tan \theta$ which is the first line of this answer and hence, nothing s...
