Write the rectangular form of the polar equation in general form.

[tex]\[ r - 7 \sin \theta = 0 \][/tex]

Assume that all variables represent positive values.

Enter only the nonzero side of the equation.

[tex]\[\square = 0\][/tex]


Sagot :

Sure, let's convert the given polar equation to its rectangular form step-by-step:

Given polar equation:
[tex]\[ r - 7 \sin \theta = 0 \][/tex]

To convert this to rectangular form, we need to use the relationships between polar and rectangular coordinates:
[tex]\[ r = \sqrt{x^2 + y^2} \][/tex]
[tex]\[ \sin \theta = \frac{y}{r} \][/tex]

First, substitute these expressions into the given equation:
[tex]\[ \sqrt{x^2 + y^2} - 7 \left(\frac{y}{\sqrt{x^2 + y^2}}\right) = 0 \][/tex]

Multiply every term by [tex]\(\sqrt{x^2 + y^2}\)[/tex] to clear the fraction:
[tex]\[ (\sqrt{x^2 + y^2})^2 - 7y = 0 \][/tex]

Simplify [tex]\((\sqrt{x^2 + y^2})^2\)[/tex] to [tex]\(x^2 + y^2\)[/tex]:
[tex]\[ x^2 + y^2 - 7y = 0 \][/tex]

Thus, the rectangular form of the given polar equation in general form is:
[tex]\[ x^2 + y^2 - 7y = 0 \][/tex]

So, we have:
[tex]\[ x^2 + y^2 - 7y = 0 \][/tex]
