Why AI Needs MathPad

Standard AI guesses at patterns. MathPad pairs it with CAS tools so every step is symbolically checked before you see it.

Missed Exact Solution

Without CAS
$e^x = \cos(x) \Rightarrow x \approx 0.739$

AI gives an approximation but misses the obvious exact solution

With CAS Tools
$x = 0$ (exact)

Missed Second Solution

Without CAS
$|2x - 3| = x + 1 \Rightarrow x = 4$

AI finds one root but misses the second valid solution

With CAS Tools
$x = 4, \frac{2}{3}$

Extraneous Root Included

Without CAS
$\sqrt{x + 3} = x - 3 \Rightarrow x = 6 \text{ or } x = 1$

AI includes x=1 which doesn't satisfy the original equation

With CAS Tools
$x = 6$ (only valid solution)
