r=9sin7θ
Replace (r,θ) by (r,θ), we get
r=9sin7(θ)
r=9sin7θ
Which is not same as original equation.
Therefore given equation is not symmetric with respect to x-axis.
Replace (r,θ) by (r,θ), we get
⇒=9sin7(θ)
r=9sin7θ
Which is same as original equation.
Therefore given equation is symmetric with respect to y-axis.
