by bigbeno37 I have used this app to review limits and derivatives since it has been many moons since I had it in college.
The app does crash occasionally, but not to point I wouldn't continue using it.
As you can see, Wolfram|Alpha can find the roots of quadratic equations.
Wolfram|Alpha shows how to solve this equation by completing the square and then solving for Wolfram|Alpha can demonstrate step-by-step solutions over a wide range of problems.
If you’re still having a hard time getting it, solve several different examples and practice identifying all the forms.
This series shows how to solve several types of Calculus limit problems.Factoring polynomials such as the difference of squares or difference of cubes help to simplify these functions into solvable limits.I know you don’t want to hear this, but practice makes perfect!Wolfram|Alpha can guide you step by step through the process of solving many mathematical problems, from solving a simple quadratic equation to taking the integral of a complex function.When trying to find the roots of 3, Wolfram|Alpha can break down the steps for you if you click the “Show steps” button in the Result pod.Special cases of limits are solved and the related graphs are described.Solving Calculus limit and derivative problems are made understandable in this guide.To solve a limit, see the 4 examples of a limit problems involving direct substitution.When graphing a solution of an equation in calculus, such as example 1, the graph will pass through the y-value 4/3 when x is the value 1.This app would be great for junior high school students through college Calculus. I especially like the play back animation for finding the solutions, nice feature for sure, for adding confidence to any student.
