Alright so I'm coding a Quadratic Equation Solver to help with my Math Class. However the teacher requires each calculation to be written out. I have the solver working, however I'm not sure where to start when it comes to printing each step. I know I will need to `System.out.println()` …

Looking for how to write code to compute for quadratic equation on a vb.net application

Hi guys. First of all, I am aware that there is a somewhat similar thread over here. However, it was never really answered and the code given was obscure (I don't like copying stuff anyway) Either way... I want to balance a chemical equation. However, I don't need help on …

I won't be asking for a source code yet. What I need to figure out is the process of a certain Math problem with the equation that seemed to be impossible to be converted to source code. Here it goes: **A certain waveform is 0 volts for time less than …

I need a code which can solve the equations like this :- 56*78+(78/8) In this we know that brackets must be solved first and then divide/multiply and then add/subtract. So, i need a code for solving this kind of equations which contains multiple operators in single line. Thnks :)

Hi, I'm trying to find a way to solve this equation with two unknowns using Python: [QUOTE](a * b) = (x * c) + (y * d) + e [/QUOTE] Where a, b, c, d and e are all floating numbers provided by the user and x and y are …

Hello...just started learning C and i'm trying to write a program that solves quadratic equations...but every time i compile and run it and enter the 3 variables it crashes. I kept on looking but didn't find anything wrong with it...help? :P [CODE]#include <stdio.h> main(){ int a,b,c; float x1,x2; printf("Please enter …

MY problem is related to entry of research data. The researchformula is entered into a textbox alongwith other usual form entries like title,subject,startdate etc. The formula consists of alzebra, trignometric, otherfunctions etc. Example [CODE] [B]x = 12; y = 24 + tit[x] + mixer[x]; z = x + sin(x) + …

hi, I am trying to make a variable equation solver using DEV-C++. I just need to know how to get C++ to solve an equation inputed by the user. So you input something like 1+1 and i need it to solve the problem and output the answer. heres an example: …

Wrote this for my college open evening just to give prospective students a taste of python. added a little "information" section just to bulk it out a bit (this section is slightly messy i know). Not sure if it works in command line, definitely works in IDLE but the command …

hi, i am using DEV-C++ and i have two problems with this code: [CODE]#include<iostream> #include<string> #include<sstream> using namespace std; int main (char argc) { string n1; getline(cin,n1); int len; len = n1.length(); int len1 = -2; int len2 = -1; for(int t = len; t>0; t--) { len1 = len1 …

Hi. Can you help me how to balance a chemical equation using linear algebra. I know how to do it on a piece of paper using the usual method of balancing. I just don't get the principle how to do it on the other method. Please give me a step …

Hey, everybody, I'm a newbie at Python (2.7.1), and new to DaniWeb as well. and the apparent simplicity of Python got me interested in programming (seriously, the only thing before this was HTML). Anyway... I was taking a test and thought that after I was finished I could make an …

Hello there! :) How should i solve for x in this equation: p*e^-x + q*sin(x) + r*cos(x) + s*tan(x) + t*x^2 + u = 0 with the user to input the values of p,q,r,s,t and u. i'm thinking of looping from 0.0001 until i-dont-know-what and then testing each value of …

how do i solve this problem r+5(r-2)=28 3(r+4)+5(r+2)=102

Hi guys.. I am currenly coding a program which outputs the next state table for flip flop circuits. I have already finished the the generator for one type of flip flop, and I have 3 more to go.. So far, my arithmetic parser is working good but I suddenly remembered …
