- 1What is the equation of the polar equation shown below?r=a*cos(nθ)
a is the maximum distance from center to outside
n is the number of petals, (remember to divide by a first)
r=2cos(4θ) - 2Convert the polar equation below to an equation in rectangular form. r=3csc θ
- 3Use the given rectangular coordinate to find a polar coordinate such that r < 0 and 0 < θ < 2π
- 4Convert the polar coordinate given below to exact rectangular form (6, 7π/4)
- 5Convert the rectangular equation below to an equation in polar form and solve for r. y = 3x -5Remember: x = rcosθ y = rsinθ, thus plug
y = 3x - 5
rsinθ = 3(rcosθ)-5
rsinθ -3rcosθ = -5
r (sinθ -3cosθ) = -5
r = -5/(sinθ - 3cosθ) - 6Write the complex number given below in exact polar form
