Alright, future engineers!
**Newton-Raphson:** Iteratively finds function roots (where f(x)=0).
Formula: `x_n+1 = x_n - f(x_n) / f'(x_n)`
Pro-Tip: A poor initial guess can lead to divergence or finding the wrong root!

Alright, future engineers!
**Bisection Method:** Finds f(x)=0 roots by repeatedly halving intervals where sign changes.
Ex: If `f(a)f(b)<0`, root's in `[a,b]`. `x_new = (a+b)/2`.
Pro-Tip: Guaranteed convergence if root is bracketed, but can be slow!

Alright, future engineers!

**Newton-Raphson** finds roots of `f(x)=0` by iteratively refining guesses.
Ex: `x_new = x_old - f(x_old)/f'(x_old)`.
Pro-Tip: A good initial guess speeds up convergence & prevents divergence!

Alright, future engineers!
**Newton-Raphson** is an iterative method to find function roots (where f(x)=0).
Formula: `x_n+1 = x_n - f(x_n)/f'(x_n)`
Pro-Tip: Your initial guess `x_0` matters! Pick one close to the root for faster convergence.

Alright, future engineers!
The **Newton-Raphson Method** iteratively finds roots (where f(x)=0) using tangent lines.
Ex: `x_n+1 = x_n - f(x_n) / f'(x_n)`.
Pro-Tip: A good initial guess `x_0` is crucial for quick convergence!

Alright, future engineers!
The **Bisection Method** finds roots by repeatedly halving an interval where `f(x)` changes sign. Ex: If `f(a)f(b) < 0`, a root is in `[a,b]`. Pro-Tip: Always converges, guaranteed if a root exists in the initial bracket!

Alright, future engineers!

**Newton-Raphson:** Finds roots for f(x)=0 using tangent lines. Ex: `x_new = x_old - f(x_old)/f'(x_old)`. Pro-Tip: Needs `f'(x)`, but converges rapidly with a good initial guess!

Alright, future engineers!
**Fixed-Point Iteration** finds a root by transforming `f(x)=0` into `x=g(x)` & iterating `x_new = g(x_old)`.
Ex: For `x^2 - x - 1 = 0`, try `x = sqrt(x+1)`.
Pro-Tip: Choosing the right `g(x)` is CRUCIAL for fast convergence!
