Thats why I love unit circle Trigonometry. The xs are 1, square root of 3. Over 2 horizontal they must be. Square root of 2 over 2 and next are, One half and zero the stately x. Secretly theyre cosine but thats coming next. O, thirty, fortyfive, sixty, ninety! Thats why I love unit circle Trigonometry.Precalculus. Solve for x cos(x)( square root of 3)2. Take the inverse cosine of both sides of the equation to extract from inside the cosine. Combine the numerators over the common denominator. Simplify the numerator. Tap for more steps Multiply by. Subtract from. Find the period. sin equals square root of 3 over 2

The neat pattern of 1, 2, 3 across the top row and 3, 2, 1 across the middle row are meant to help you memorize the table values. Keep in mind that the square root of 1 is just 1, so, for instance, . To find the tangent, you'd divide the sine value by the cosine value.

If the sin 60 is square root 3 over 2, then the cos. 30; 1 over 2 60; square root 2 over 2 30; square root 3 over 2 60; 1. The answer to your question is cos 30 The cosine is a trigonometric function. The cosine of an angle is done by dividing the length of a side of a traingle adjacent to the acute angle by the length of the longest side or the hypotenuse. For a complete list of angles and It helps if one recognises the lengths 3 and# sqrt2# as being two of the sides in one of the special triangle, namely 30, 60 90. Sketch this by drawing an equilateral triangle of sides 2 units, and drawing in a line of symmetry to form two rightangled triangles.**sin equals square root of 3 over 2** Cos: negative square root of 2 over 2. Radian: 3 pi over 4. Tan: negative 1 over square root of 3
