Desmos Graphing Calculator vs Proportion_Calculator

Explore math with the fast and powerful Desmos Graphing Calculator. Plot any equation, from lines and parabolas to derivatives and Fourier series. Add sliders to demonstrate function transformations, create tables to input and plot data, animate your graphs, and more—all for free. Features: Graphing: Plot polar, cartesian, or parametric graphs. There’s no limit to how many expressions you can graph at one time—and you don’t even need to enter expressions in y= form! Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph. Tables: Input and plot data, or create an input-output table for any function. Statistics: Find best-fit lines, parabolas, and more. Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window. Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger. Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. It can handle square roots, logs, absolute value, and more. Inequalities: Plot Cartesian and polar inequalities. Accessibility: Read and edit math using a screen reader or a refreshable Braille display, and use audio trace to explore graphs and data through sound. Offline: No internet access required.

Proportion calculator This application is designed to find the “x” or “unknown” value in a proportion of two ratios. It does so while providing the labeled steps that help the user to understand proportions deeply. It also goes by the name solving proportions calculator. To know more about the proportions and this app, keep reading. What are proportions? 
Proportions show a relation between two different ratios. These ration seem different but are actually related in similar way. Proportions have many uses because if you know one ratio you can find the values of other proportions. It has its application everywhere from baking to higher sciences. Example: The tv cooking shows often provide an ingredient list of 4 to 5 servings. If you want to make more servings then proportion calculator will be useful in finding the quantity of ingredients. Proportion formula: There is no formula to solve proportions. It is just a matter of writing and simplifying. Say there are two ratios (a) 2:3 and (b) 7:x To find the value of x in the second proportion: 1. Write the ratios in fraction form. 2. Cross multiply. 3. Separate the x and solve. This will give the missing value. How to use the proportion solver? The application is easy to operate due to its up-to-the-mark useability. 1. Enter the ratios in the correct order, first goes first. 2. Remember to enter the unknown value as x. 3. Click “Calculate”. Features: You will understand why the claim is that “This is one of the best proportion solvers” once you install and try it. Its main highlights are: 1. It is to the point with no extra buttons and options to complicate things. 2. The answer is calculated very fast so it is time-saving. 3. Smart color theme which is easy on the eyes. 4. Math keyboard for convenient inputting.
