How Deep Is the Well? Exploring Physics with Code Have you ever dropped a rock into a well and wondered how deep it is? The sound of the splash echoes back, but how can we calculate the depth without physically measuring it? Let’s dive into the fascinating world of physics and programming to solve this age-old question using Function Calculator.   The Science Behind It When you drop an object into a well, two key events occur: The Fall : The object falls under the influence of gravity, accelerating as it goes. The Sound : After hitting the water, the sound of the splash travels back up to you. By combining these two events, we can calculate the depth of the well using basic physics. The total time  t  (the time it takes for you to hear the splash) is a combination of: The time it takes for the object to fall (fallTime). The time it takes for the sound to travel back up ( soundTime ). Using these principles, we can derive a quadratic equation to calculate the depth. The Fo...

How to Create Custom Functions for Solving Math Problems in Your Calculator Hello, calculator enthusiasts! Today, I’m going to walk you through how you can create a custom function in your calculator to solve specific math problems. If you're dealing with  2x2 systems of linear equations , this guide is for you. We'll use the provided code as an example and break it down step by step. The Problem: Solving a 2x2 System of Linear Equations A 2x2 system of linear equations looks like this: a * x + b * y = m c * x + d * y = n Here,  a ,  b ,  c , and  d  are coefficients, and  m  and  n  are constants. Your goal is to solve for the variables  x  and  y . To do this, we'll use determinants. The Code Breakdown Let’s dive into the code you provided and explain how it works. Step 1: Calculating the Determinant of a 2x2 Matrix The determinant of a 2x2 matrix is calculated using the formula: det = (a * d) - (b * c) In the code, this...
