Explanation Given information: 1 − 2 Sin 2 75 ° Calculation: We have the double angle identity as; Cos 2 x = 1 − Sin 2 x The given expression is the right side of the above double angel identity, where x = 75 ° . Thus according to the above double angel identity, we can write the given expression as, 1 − 2 Sin 2 75 ° = Cos 2 ( 75 ° ) r e p l a c e x w i t h 75 ° ⇒ 1 − 2 Sin 2 75 ° = Cos 150 ° = Cos ( 180 ° − 30 ° )

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
