According to Wolfram it is approx. -1.895
How do I find the exact value of the root though?

Khashishi said:What makes you think it is a root? It probably is transcendental.
Of course, 0 is an exact solution, and +1.895 is also approximately a solution.
I don't believe there is a way to find the exact value of the root that is near either -1.895 or +1.895. You can approximate either of these roots to whatever precision is needed using any number of numerical techniques, such as Newton's Method, Newton-Raphson, bisection, and others.greswd said:According to Wolfram it is approx. -1.895

Wiki says the following:Samy_A said:I think it is transcendental as a consequence of the Lindemann–Weierstrass theorem.
To solve for x in this equation, you can use algebraic manipulation and trigonometric identities. Multiply both sides of the equation by 2 to get x = 2sinx. Then, use the identity sin(2x) = 2sinxcosx to rewrite the equation as x = sin(2x). Finally, use a graphing calculator or table of values to approximate the solution.
No, you cannot use a calculator to find the exact value of x/2 = sinx. The solution to this equation is not a rational number and cannot be expressed in terms of simple fractions or decimals. It requires the use of trigonometric identities and approximations to find the closest value.
There are infinitely many solutions for x in this equation. Since the graph of y = x/2 and the graph of y = sinx intersect an infinite number of times, there are an infinite number of values of x that satisfy this equation.
No, there is no general formula for finding the exact value of x/2 = sinx. Each solution requires the use of different trigonometric identities and approximations. However, you can use a graphing calculator or table of values to approximate the solution.
Yes, there are some special cases for finding the exact value of x/2 = sinx. For example, when x = 0, the equation becomes 0/2 = 0, which has a simple solution of x = 0. Additionally, the solutions for x in this equation will repeat in a pattern of 2π, so you can use this to find other solutions.
