Solve - Graphing Calculator at Mac App Store analyse

Solve is a calculator like no other! Solve solves expressions as you type and features an innovative memory system to store and recall answers. Simply touch the answer to store it and touch the stored answer to use it in an expression. Solve has four tabs that select four different calculators each with its own color. Multiply numbers, calculate a tip and find a square root all without clearing your results! Plot graphs with a single touch! Solve plots 2D and 3D functions using the x, y and θ variables. When you use the x, y and θ variables in an equation the answer will say Touch to Plot. Touch this label to graph the equation. GRAPHING Plot functions using the x variable. For example, "y=sin(x)" is just entered as "sin(x)". • cos(x) • abs(x) • x^2+2x+6 POLAR GRAPHING Plot polar equations using the θ variable. For example, "r=2θ" is just entered as "2θ". • 2θ • sin(2θ) 3D GRAPHING Plot 3D functions by using the x and y variables. For example, "z=x+y" is just entered as "x+y". • cos(x)+sin(y) • x^2+y^2 PLOT MULTIPLE GRAPHS Graph multiple functions by separating each equation with a comma. • sin(x),cos(x) • x,x^2,x^3 TIME GRAPHING The T variable is used to create animated or time plots. • cos(x+T) • sin(x+T)*x • cos(x+T)+sin(y+T) USER REVIEWS Really nice calculator by NeedHim "Having multiple calculators that you can use your calculations in is really a cool function. Prevents you from having to have a pad and paper to figure out multiple calculations. Also the colors are just incredible." Simply amazing. by oddgoingson "I was blown away by this app. When I first tried it and the tutorial came up, my first instinct was to skip past it. Then I started... Blown away. This calculator has everything and more. It is so logical for those who always wondered why calculators are sometimes so archaic. Forget copy and paste. Then I got to the graphing.... A must have period!" Perfect! by Michael "Ive always hated how calculators didnt save answers. It made working out equations very hard and time consuming. But this app does that, and it does it well! Finally, a calculator app that actually works." Outstanding calculator -- full featured! by ofloveandhate "I have been using Solve for a few years now. Prompt updates, excellent controls, and a ton of features make it the best calculator I have used. I love having four separate units which I can use in each other and the plotting is easy as pi." Great app by biosci "It does everything I need in a fun way thats intuitive to how I think and operate. Ill take it!" Great Calculator by Carl E. M. "This is a great calculator, aesthetically and functionally. Having the answer appear as you enter numbers will be the future of all calculators." I love this calculator by Alan63134 "I work on a shipping dock and it saves me a lot of time and headache. I can have 4 different calculator in one place. I can see the different weights or counts and know where I am if I have to do a lot of weighing or counting on different pallets. I use it every day. I also use it while shopping and can add the price of my shopping list and calculate what things cost. I love this calculator." Awesome! by smart-music-fan "This app is great. It easily graphs functions on the xy plane, and adding T as a variable to make the graph move is so fun. Its 3D graphing capability is great - quick, easy (it sets nice bounds on the z axis so you can see things clearly), and helpful for visualizing my Multivariable Calculus homework." Fantastic by xTricksterz "This app is beautiful, I use on my iPad and Im first to answer most of the problems in class. This app shreds TIs calculator OS." Awesome!!! by llikeadodachacha "Does just about everything my TI-84 Plus but quicker and much easier to manipulate the graphs. It loads instantly and the 3D function is awesome for higher level math classes (Im in Calc 3 now and its already come in hand!)
