Evaluate mathematical functions at given values with step-by-step solutions and graph analysis.
A function is a relation that assigns exactly one output for each input. In mathematics, functions are used to model relationships between variables.
Can I use trigonometric or exponential functions?
Yes, you can enter functions like sin(x), cos(x), e^x, etc.
What if I enter an invalid function?
The calculator will show an error if the function cannot be evaluated.
