Web1 Answer. The starting and finishing angles for θ ∈ [ 0, 2 π] defining your inner loop are defined by sin [ θ] = − 1 2, which gives θ m i n = 7 π 6 and θ m a x = 11 π 6 . The area within the inner loop is then given by. A = ∫ θ m i n θ m a x 1 2 r 2 ( θ) d θ = ∫ 7 π 6 11 π 6 1 2 ( 1 + 2 sin ( θ)) 2 = ∫ 7 π 6 11 π 6 d ...

WebApr 8, 2024 · First we need to set these equations equal to one another and solve for theta and we will find that these two polar curves intersect at pi/4. Now we need to use integration to find the area and this can be set up by doing 1/2 times the integral from 0 to pi/4 of (3sinθ)^2 + 1/2 times the integral from pi/4 to pi/2 of (3cosθ)^2 which will give you 1.284. WebSep 25, 2014 · The equation of the tangent line is y=0 (in red), which looks like this. Let us look at some details. Let us find the coordinates (x_1,y_1) of the point when theta=2pi. Since {(x(theta)=sin(2 theta)cos theta),(y(theta)=sin(2theta)sin theta):}, we have (x_1,y_1)=(x(2pi),y(2pi))=(0,0). Let us now find the slope m of the tangent line. By … WebSo I have computed $$\frac{dx}{d\theta} = \frac{\cos{3\theta}}{r}$$ and $$\frac{dy}{d\theta} = \frac{\sin{3\theta}}{r}$$ I set these equal to zero and found the horizontal tangents to … dr phil hall
