Solution We can use a method similar to the one used to solve Example 1.8 in Section 1.2. That is, draw a right triangle and interpret cos θ as the ratio adjacent hypotenuse of two of its sides. Since cos θ = − 4 5, we can use 4 as the length of the adjacent side and 5 as the length of the hypotenuse.
http://help.mathlab.us/134-trigonometric-values-of-15-degrees-and-its-multiples.html Webwe see 'x' and 'c' to be squared i.e. 2*x^2 = c^2 If you recall studying 'Real Numbers' or 'Indices', you would know that the root of 'x^2' is 'x' , the root of 'c^2' is 'c' and of '2' is ' (root sign)2'. So by simply finding root of both side: 2*x^2 = c^2, will be (root)2*x = c and so we write it as : x* (root)2 = c,
