Answer:
The polar form is <em> sinθ = 2 r³cos⁴θ </em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given function y = 2 x⁴
<em>Parametric Form x = r cosθ ....(i)</em>
<em> and y = r sinθ ....(</em>ii)
squaring x² = r² cos ²θ
y² = r² sin²θ
adding x² + y² = r² cos ²θ+r² s in²θ
= r²( cos ²θ+s in²θ)
= r²( 1)
<em> x² + y² = r²</em>
<em> </em>Given function y = 2 x⁴
Now convert into polar form
<em> r sinθ = 2 (r cos θ )⁴</em>
<em> r sinθ = 2 (r )⁴cos θ )⁴ </em>
<em> sinθ = 2 r ³cos⁴θ </em>
