Two new modules in EngKit Pro: • Projectile Motion: animate a launch and get range, peak height, flight time and impact speed. Pick gravity from Earth, the Moon, Mars or Jupiter, and pause or scrub through the flight. • Boolean Algebra: simplify logic expressions with a truth table and a Karnaugh map. See each group in color, the result explained in plain words, and its sum-of-products, product-of-sums and minterm forms. Plus a new Physics category on the home screen.

Two new Pro modules: • Triangle Solver: solve any triangle from three values (including the ambiguous case), right triangles, and trig functions. • Root Finder: find roots of any f(x) with bisection, false position, Newton-Raphson and secant, with a graph and a step-by-step iteration table.
