Convert the equation to rectangular form.
r(-2sinϴ+cosϴ)=5

• -2√(x²+y²)=5
• -2y+x=5
• -2x+y=5
• √(x²+y²)(y+x)=5

Convert the equation to rectangular form.
cos²ϴ=(3/2)r - sin²ϴ

• x = (3/2)(x²+y²) - y
• 1 = (3/2)(x²+y²)
• (2/3) = √(x²+y²)
• 1 = (2/3)(x²+y²)

Convert the equation to rectangular form.
7r = 3sinϴ

• (7/3)(x+y) = x
• (7/3)(x²+y²) = x
• 7√(x²+y²) = 3y
• 7(x²+y²) = 3y
