我需要帮助在bluej中创建方程式 [英] I need help creating an equation in bluej

问题描述

我可以弄清楚如何提示用户为N输入正确的变量，但我不知道如何使用给定的输入创建正确的方法来解决方程式N



等式是θ=（n-2）/ 2 * 180°



我尝试过：



我试过谷歌搜索并解构另一项任务，我必须提示用户输入变量a，b，c并通过二次方程运行变量并给出根作为输出

解决方案

你只需按照等式说明：

  float  theta; 
  float  N; 
  //  从用户获取N的值 
 N = N  -   2 。 0 ; 
 N = N /  2 。 0 ; 
 theta = N *  180 。 0 ; 

I can figure out how to prompt the user to enter the correct variable for N but I dont know how to create the correct method to solve the equation with the given input for N

The equation is θ = (n-2)/2 * 180°

What I have tried:

I have tried googling it and deconstructing another assignment I had where I had to prompt the user to enter variables a, b, c and run there variables through the quadratic equation and give the roots as the output

解决方案

You just do what the equation states:

float theta;
float N;
// get value of N from user
N = N - 2.0;
N = N / 2.0;
theta = N * 180.0;
