- TL;DR Summary
- What are the mistakes made when you try to solve equations for some variable/s but end up with an identity?
This might be a bit vague but when solving algebra equations, what does it 'mean', or what mistakes does it imply if you end up with both sides of the equation being the same thing and getting nowhere? For example, you want to solve a system for x, but the x's end up cancelling and you get 0=0.
For context I was just doing some basic projectile motion stuff - wanted to find minimum speed at which a ball thrown at a given angle would always collide with another dropped at the same instant but ended up constant = constant.
But I've run into the same issue many times before and never properly learnt what I was doing wrong whenever it happened.
