The main issue is that it won't find zeros where to function only touches the x-axis without crossing (e.g. Desmos online calculator Desmos is a free online calculator that does graphing and much more. With this you can check a large number of small intervals across the domain of a function to approximate where its zeros are. The second method is to use the Intermediate Value Theorem, which states that if the sign of a continuous function changes between the bounds of a given interval, then there exists at least one zero in that interval. The first one is to use desmos' built in regression feature which is designed for finding curves of best fit for data sets but can be used to find solutions to equations in general and u/Torchere's comment shares a method for using that. In general, it is not possible to find all the zeros of any functions exactly but there are some methods for approximating them.

This superposition allows for arbitrary charge distributions.Finding the intersections of the curves of two functions, f(x) and g(x) is analogous to finding the zeros of the function of their difference, f(x) - g(x). Additional information can be found on the Learn Desmos page. Use it to plot data, graph functions, evaluate equations, and create classroom activities. You can, though, superimpose the angles (arctans) multiplied by the charges and take the tan of both sides (similar to what you did for the simplified real and imaginary parts). The Desmos Graphing Calculator is a free online math tool widely used by teachers and students to plot equations and learn math concepts. The field line 'potential' also allows superposition, but you possibly also observed problems with the arctan function and its return of the principal value, where the discontinuity at pi and -pi can cause contour problems. I think the technique is more powerful than you might realize, at least as indicated by your Desmos graph, where you appear to rely on Wolfram Alpha to simplify expressions for special cases. In case you are not aware, it is discussed in the classic text 'Complex Variables and Applications' by Churchill and Brown. Feel free to post demonstrations of interesting mathematical phenomena, questions about what is happening in a graph, or just cool things you've found while playing with the graphing program.

Introduction to the Desmos Graphing Calculator. A subreddit dedicated to sharing graphs created using the Desmos graphing calculator. The following functions require a list of numbers to be added first. Desmos Graphing Calculator Follow the instructions here to create Desmos graphs This is a math teacher favorite, but tools like ca The results also include information on age, gender, face shape, facial expression, skin color and more But if you want programmable non-graphing, that is CASIO fx-5800P, but looks like a graphing calculator. Students will share their ideas using card sorts, sketches, images, multiple choice responses, and a large and growing list of other components.

Get started with the video on the right, then dive deeper with the resources below. Browse our collections of free, engaging, and customizable activities thatвЂ™ll help you invite, celebrate, and develop your studentsвЂ™ thinking. It should be emphasized that this technique only applies in the strictly 2D case. Welcome to the Desmos Graphing Calculator Graph functions, plot data, evaluate equations, explore transformations, and much moreall for free. Thank you for giving it attention - nice work!
