How do you graph the polar curve r 4sinθ
WebDec 12, 2016 · In Cartesian plane draw a circle with center at (0,3) and radius 3. Explanation: The relation between polar coordinates (r,θ) and Cartesian coordinates (x,y) is x = rcosθ, y = rsinθ and r2 = x2 +y2. We can use this to convert equation in polar coordinates to an equation with Cartesian coordinates. r = 6sinθ ⇔ r2 = 6rsinθ or x2 +y2 = 6y WebExample 7.16 involved finding the area inside one curve. We can also use Area of a Region Bounded by a Polar Curve to find the area between two polar curves. However, we often need to find the points of intersection of the curves and determine which function defines the outer curve or the inner curve between these two points.

WebNov 10, 2024 · In polar coordinates we define the curve by the equation r = f(θ), where α ≤ θ ≤ β. In order to adapt the arc length formula for a polar curve, we use the equations x = rcosθ = f(θ)cosθ and y = rsinθ = f(θ)sinθ, and we replace the parameter t by θ. Then dx dθ = f′ (θ)cosθ − f(θ)sinθ dy dθ = f′ (θ)sinθ + f(θ)cosθ.
