How this is calculus is beyond me. Set $4x = \tan(x)$ and solve for x.

Although it's not that simple because an iterative method must be used.

Since I'm too lazy to find a solution wolfram can do it for me: 4x&#x3d;tan&#x28;x&#x29; - Wolfram|Alpha

3. ## ha,

you must be in the same math class as me! 1550 lsu?
