Show that $x^2-\\cos(x)$ has two roots in the real numbers
WebSince cot(x) is the reciprocal of tan(x), tan^2(x) = 1/cot^2(x). In step 4 we write cot^2(x)/cot^2(x) in place of 1, since this will give us a common denominator within the square root. In step 5, with the common denominator cot^2(x), we are able to combine the numerators into one fraction. WebSimplify cot(x)cos(x) Step 1. Rewrite in terms of sines and cosines. Step 2. Multiply.
