benorin said:Here are a few websites that have online calculators:
www.quickmath.com - powered by webMathematica: this site is very handy and will do algebra (factoring, simplify, partial fraction decomposition, expand), solve equations/inequalities (single or a system), plot equations/inequalities (single or a system), derivatives, definite or indefinite integrals, and do matrix arithmetic/inverses/determinants.
www.integrals.com - powered by the Mathematica engine: just what it seems, but it will only do indefinite integrals.
www.livephysics.com - has these tools: Evaluate Function, Function Grapher, 3D Function Grapher. Very nice since the 3D Function Grapher allows for you to plot a 3D function and then cut and paste customized UBB code from the page into a forum post to embed the plot graphic you made into your post (see add).
http://people.hofstra.edu/faculty/Stefan_Waner/RealWorld/utilsindex.html - includes these categories of utilities/tools: Graphers, Regression Tools, Matrix and Linear Algebra Tools, Probability and Statistics Tools, Calculus Tools, Math of Finance Tools, and Miscellaneous.
An online 3D graph view of 2-variable functions is a digital representation of a mathematical function that shows the relationship between two variables in three dimensions. It allows users to visualize and manipulate the function to better understand its behavior.
An online 3D graph view of 2-variable functions is useful for studying and analyzing mathematical functions, as it provides a visual representation that can reveal patterns and relationships that may not be apparent from a numerical or algebraic representation. It can also be used for teaching and learning purposes in mathematics and other related fields.
Using an online 3D graph view of 2-variable functions can help users gain a better understanding of the behavior and properties of a function. It can also make it easier to identify key features such as critical points, intercepts, and symmetry. Additionally, it allows for quick and easy manipulation of the function to test different scenarios and make predictions.
An online 3D graph view can be used to graph a variety of 2-variable functions, including linear, quadratic, exponential, trigonometric, and logarithmic functions. It can also handle more complex functions, such as parametric equations and implicit functions.
One limitation of using an online 3D graph view is that it may not accurately represent all aspects of a function, as the visual representation is a simplified version. It also requires a good understanding of the underlying mathematical concepts to interpret the graph correctly. Additionally, some functions may be too complex to graph effectively in this format.
