Do parameters in equations scare you? This will change the way you look at math!

Imagine having a tool in your hands that helps you tackle even the trickiest equations with parameters. Calculio is the first and only app in the world designed to help you with this!
Why are parameters so intimidating?
- It’s not just one equation but an entire family of equations.
- Each value of the parameter can change the type of equation.
- You need to keep track of several conditions at once.
- One mistake, and the entire solution is wrong.
What Calculio does for you:
- Automatically determines the domain of definition.
- Considers all edge cases.
- Alerts you to forbidden operations (divide by zero? Not with us!).
- Checks conditions for solvability.
- Creates a clear discussion table.
- Performs verification for non-equivalent operations.
UNIQUE ADVANTAGE: We are the only app in the world that helps you handle parameters!
No more: “Where do I even start?”, “What if the parameter is zero?”, “How do I know I didn’t miss anything?”, “Where should I do the verification?”
Ready to conquer the world of parameters?
P.S.: Your math teacher will be shocked by how well you understand parameters!
