What is the reason that every quintic equation is convertible into the bring-jerrard's normal form using the Tschirnhaus transform? It seems to be impossible but isn't... Why is it so? Why don't this transform change the solutions?Don't spam!!! |

Answer» Answer: The value of –1 <= cosθ <=1 So, there is no real θ for which the value of cosθ = 4.996. So, the complex and IMAGINARY solution for the above question is θ = ±2.2916i where, i = √(–1) Refer the attachment for the solution And, the value of θ for cosθ = 0.4996 => θ = 60° 1' 35'' |
