WebA polar equation describes a curve on the polar grid. The graph of a polar equation can be evaluated for three types of symmetry, as shown in Figure 6.2.2. Figure 6.2.2: (a) A graph is symmetric with respect to the line θ = π 2 (y-axis) if replacing (r, θ) with ( − r, − θ) yields an equivalent equation. WebOct 19, 2024 · The area we seek is shaded in grey. Let us first find the points of intersection: 4 + 4cosθ = 6. ∴ 4cosθ = 2. ∴ cosθ = 1 2. ∴ θ = ± π 3. We calculate area in polar coordinates using : A = 1 2 ∫ β α r2 dθ. The area bounded by r = 4 + 4cosθ and r = ± π 3 is:

WebApr 24, 2016 · pi Draw both curves on the same graph paper. Notice that the cardioid intersects with the circle at (3/2,pi/6), (3/2,(5pi)/6) and the pole. The area of interest has been shaded above. To find the area of a polar curve, we use A = 1/2 int r^2 "d"theta We find the area of the cardioid and the circle separately on the interval pi/6 < theta < … WebFeb 16, 2024 · Conversion of Polar to Rectangular form is easy. To convert polar to rectangular form, follow the below steps: Step 1: List down the polar equations with r, θ angle, and variables x, y. x = r cos θ (eq1) y = r sin θ (eq2) Step 2: Careful consider the situation, where theta angle can be eliminated. Squaring eq1 we get: WebApr 14, 2024 · r = 8sinθ ∴ r ⋅ r = r ⋅ 8sinθ or. r2 = 8rsinθ ∴ x2 +y2 = 8y or. x2 +y2 − 8y = 0 or x2 + y2 −8y + 16 = 16 or. x2 +(y − 4)2 = 42. Rectangular form is x2 + (y − 4)2 = 42. graph {x^2+ (y-4)^2=16 [-20, 20, -10, 10]} Answer link. head ti radical 42lbs 45lbs
