Question

Find the symmetry of curve 2( − ) = 3.

Answer 1

Answer:

Equations can have symmetry: x^2. Graph of x2. Symmetry about y-axis ... −y = x3. Now try to get the original equation: Try multiplying both sides by −1

Answer 2

Answer:

Given r

2

=cos(θ) , which is equivalent to r

3

=rcosθ

⇒(x

2

+y

−x

2

=0 , let it be f(x,y)

Here f(x,y)=f(−x,y) and f(x,y)=f(x,−y) and f(x,y)=f(−x,−y)

Therefore it has x axis symmetry , y axis symmetry and symmetry with respect to origin

Therefore the correct option is A,B,C
