သခ်ၤာ/ရူပ/ဓာတု/ပထ၀ီ ေက်ာင္းသားေတြလိုအပ္ေနတဲ့ေဆာ့၀ဲေလး Graphing Calculator by Mathlab ေလးပါ
ဗ်ာ ပ့ုံမွာၾကည့္တာနဲံ ဘာေတြပါ၀င္လဲသိမွာပါ အဆင္ေပျပမဲ့ေဆာ့၀ဲေကာင္းေလးပါ (ပုသိမ္အိုင္တီ)
Graphing calculator with algebra. Essential tool for school and college. Replaces bulky and expensive handheld graphing calculators.
Multiple functions on a graph, polar graphs, graphing of implicit functions, values and slopes, roots, extremes, intersections. Algebra: polynomials, polynomial equation solving, matrices, fractions, derivatives, complex numbers and more. Shows results as you type. Use menu to switch between modes.
Free version requires internet connection and contains ads! $5.99 in-app upgrade to PRO. Contact us if you need multiple licenses for a school or organization.
