Values of Trigonometric Ratios of Typical Angles 1.Value of sin15°, cos15°, sin75°, cos75°, tan15°, tan75°: (i) sin15° sin15° = sin (45° – 30°) = sin45° cos30° – sin30° cos45° . . (ii) cos15° cos15° = cos (45° – 30°) = cos45° cos30° + sin30 sin45° . cos15° = . Also, sin15° = cos75° = -cos105° Read more about Values of Trigonometric Ratios of Typical Angles[…]
