get an 6 input from users 3 voltage phasors and 3 current phasors and plot the phasors and find its sequence components in javascript

To get 6 inputs from users, you can use the prompt function in JavaScript. Here's an example of how you can prompt the user for 6 inputs:

index.tsx
// Prompt the user for 6 inputs
const voltagePhasors = [];
const currentPhasors = [];
for (let i = 1; i <= 3; i++) {
  const voltage = prompt(`Enter voltage phasor ${i} (in polar form):`);
  const current = prompt(`Enter current phasor ${i} (in polar form):`);

  voltagePhasors.push(parsePhasor(voltage));
  currentPhasors.push(parsePhasor(current));
}

// Parse the polar form of the phasor into its components
function parsePhasor(input) {
  const parts = input.trim().split(/[\s,]+/);
  const magnitude = parseFloat(parts[0]);
  const angle = parseFloat(parts[1]);

  return {
    magnitude,
    angle
  };
}

Once you have the user inputs stored as voltagePhasors and currentPhasors, you can use a plotting library like Chart.js to plot the phasors. Here's an example of how to create a scatter plot using Chart.js:

index.tsx
// Create a scatter plot
const ctx = document.getElementById('myChart').getContext('2d');
const chart = new Chart(ctx, {
  type: 'scatter',
  data: {
    datasets: [{
      label: 'Voltage Phasors',
      data: voltagePhasors.map(phasor => ({
        x: phasor.magnitude * Math.cos(phasor.angle),
        y: phasor.magnitude * Math.sin(phasor.angle)
      })),
      pointBackgroundColor: 'blue',
    }, {
      label: 'Current Phasors',
      data: currentPhasors.map(phasor => ({
        x: phasor.magnitude * Math.cos(phasor.angle),
        y: phasor.magnitude * Math.sin(phasor.angle)
      })),
      pointBackgroundColor: 'red',
    }]
  },
  options: {
    scales: {
      x: {
        type: 'linear',
        position: 'bottom'
      },
      y: {
        type: 'linear',
        position: 'left'
      }
    }
  }
});

To find the sequence components of the phasors, you can use the formulas for positive, negative, and zero sequence components in power systems. Here's an example of how to calculate the sequence components using JavaScript:

index.tsx
// Calculate sequence components
const a = complex(Math.cos((2 * Math.PI) / 3), Math.sin((2 * Math.PI) / 3));

const positiveSequence = [];
const negativeSequence = [];
const zeroSequence = [];

for (let i = 0; i < 3; i++) {
  const va = voltagePhasors[i];
  const ia = currentPhasors[i];

  const vp = complex(va.magnitude, va.angle);
  const ip = complex(ia.magnitude, ia.angle);

  const vn = complex.mul(a, vp);
  const in = complex.mul(a, ip);

  const vz = complex.mul(a, vn);
  const iz = complex.mul(a, in);

  positiveSequence.push({
    voltage: polarForm(vp),
    current: polarForm(ip)
  });
  negativeSequence.push({
    voltage: polarForm(vn),
    current: polarForm(in)
  });
  zeroSequence.push({
    voltage: polarForm(vz),
    current: polarForm(iz)
  });
}

// Complex number class
function complex(real, imaginary) {
  return {
    real,
    imaginary,
    add: function (other) {
      return complex(this.real + other.real, this.imaginary + other.imaginary);
    },
    mul: function (other) {
      return complex(
        this.real * other.real - this.imaginary * other.imaginary,
        this.real * other.imaginary + this.imaginary * other.real
      );
    }
  };
}

// Convert a complex number to polar form
function polarForm(complexNumber) {
  const magnitude = Math.sqrt(
    complexNumber.real ** 2 + complexNumber.imaginary ** 2
  );
  const angle = Math.atan2(complexNumber.imaginary, complexNumber.real);

  return {
    magnitude,
    angle
  };
}

Note: In the above example, I have used the complex function to represent complex numbers and polarForm function to convert complex numbers to polar form. These functions are not built-in JavaScript functions, so you need to define them yourself.
