WebThe question was asking for the intersection points of r = 1 + cos θ and r = 1 − cos θ with 0 ≤ θ ≤ 2 π, but doing: 1 + cos θ = 1 − cos θ. 0=2cosθ. 0=cosθ. θ= π 2 or 3 π 2. Yields an incomplete answer. When the two curves are graphed a third intersection appears at the pole, but at two separate angles for each graph. θ=π ...

WebOct 10, 2014 · y'(θ) = cosθ ⋅ sinθ +(1 +sinθ) ⋅ cosθ. = 2sinθcosθ +cosθ. = sin2θ + cosθ. ⇒ y'( π 4) = sin( π 2) + cos( π 4) = 1 + 1 √2. The slope m we are looking for is: m = dy dx ∣θ= π 4 = y'(π 4) x'(π 4) = 1 + 1 √2 − 1 √2 = − (√2 +1) I hope that this was helpful. Answer link.
