WebApr 30, 2024 · How can you algebraically calculate the exact value of a trig function applied to a non-transcendental angle value? I know that for certain angles (e.g. 75°), you can represent them as a sum/difference of two angles with nice, algebraic trig function results (in this case, 75° = 30° + 45°). ... Want to solve for $\mathrm{sin(\theta)}$, at ... 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,
