WebOr, you can calculate tan (75°) by applying the addition formula for tangents: tan (75°) = (tan (30°) + tan (45°))/ (1 - tan (30°)*tan (45°)) = . Simplify it: . Thus, both calculations produce the same result for tan (75°), namely, . Example 2 Find cos (15°), sin (15°) and tan (15°). Solution Note that 15° = 45° - 30°. WebAddition formulae When we add or subtract angles, the result is called a compound angle. For example, \ (30^\circ + 120^\circ\) is a compound angle. Using a calculator, we find: \ [\sin...
