Therefore, the rectangular form of the equation is ( x^2 + y^2 = \cos(\theta) \To convert ( r^2 = \cos \theta ) to rectangular form, use the trigonometric identity ( x = r \cos \theta ) for the xcoordinate and ( y = r \sin \theta ) for the ycoordinate in polar coordinates.
So, for ( r^2 = \cos \theta ):
Square both sides to get ( r^2 = \cos^2 \theta ). Using the Pythagorean identity ( \cos^2 \theta + \sin^2 \theta = 1 ), substitute ( 1  \sin^2 \theta ) for ( \cos^2 \theta ). NowTo convert the equation ( r^2 = \cos(\theta) ) to rectangular form, use the relationships between polar and rectangular coordinates:
 ( r^2 = x^2 + y^2 ) (from the conversion of polar to rectangular coordinates)
 ( \cos(\theta) = \frac{x}{r} ) (from the definition of cosine in terms of polar coordinates)
Substitute equation 2 into equation 1:
( x^2 + y^2 = r^2 = \cos(\theta) )
Therefore, the rectangular form of the equation is ( x^2 + y^2 = \cos(\theta) ).To convert ( r^2 = \cos \theta ) to rectangular form, use the trigonometric identity ( x = r \cos \theta ) for the xcoordinate and ( y = r \sin \theta ) for the ycoordinate in polar coordinates.
So, for ( r^2 = \cos \theta ):
Square both sides to get ( r^2 = \cos^2 \theta ). Using the Pythagorean identity ( \cos^2 \theta + \sin^2 \theta = 1 ), substitute ( 1  \sin^2 \theta ) for ( \cos^2 \theta ). Now,To convert the equation ( r^2 = \cos(\theta) ) to rectangular form, use the relationships between polar and rectangular coordinates:
 ( r^2 = x^2 + y^2 ) (from the conversion of polar to rectangular coordinates)
 ( \cos(\theta) = \frac{x}{r} ) (from the definition of cosine in terms of polar coordinates)
Substitute equation 2 into equation 1:

Therefore, the rectangular form of the equation is ( x^2 + y^2 = \cos(\theta) ).To convert ( r^2 = \cos \theta ) to rectangular form, use the trigonometric identity ( x = r \cos \theta ) for the xcoordinate and ( y = r \sin \theta ) for the ycoordinate in polar coordinates.
So, for ( r^2 = \cos \theta ):
Square both sides to get ( r^2 = \cos^2 \theta ). Using the Pythagorean identity ( \cos^2 \theta + \sin^2 \theta = 1 ), substitute ( 1  \sin^2 \theta ) for ( \cos^2 \theta ). Now, you have ( r^2 = 1  \sin^2 \theta ). Rearrange the equation to isolate ( \sin^2 \theta ): ( \sin^2 \theta = 1  r^2 ). Take the square root of both sides to solve for ( \sin \theta ): ( \sin \theta = \sqrt{1  r^2} ).
Now, you have the values for ( \cos \theta ) and ( \sin \theta ). You can use these values to convert to rectangular form:
[ x = r \cos \theta ] [ x = r \sqrt{\cos^2 \theta} ] [ x = r \sqrt{1  \sin^2 \theta} ] [ x = r \sqrt{1  (1  r^2)} ] [ x = r \sqrt{r^2} ] [ x = r^2 ]
So, ( r^2 = \cos \theta ) in polar form can be converted to ( x = r^2 ) in rectangular form.
