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, list of commonly prescribed rsa inhibitorsWebTo solve a trigonometric simplify the equation using trigonometric identities.
