Interactive Capabilities

• Algebra Mode: Solves linear expressions, isolates variables, simplifies polynomials, and computes roots of quadratic equations using the discriminant formula.
• Trigonometry Mode: Computes circular functions (sine, cosine, tangent), reciprocal identities (secant, cosecant, cotangent), and inverse trigonometric functions in degrees or radians.
• Calculus Mode: Computes analytical first-order derivatives symbolically, visualizes instantaneous slope, and graphs resultant functions.
