A semicircle with diameter PQ sits on an isosceles triangle PQR to form a region shaped like a two-dimensional ice-cream cone, as shown in the figure. If A ( θ ) is the area of the semicircle and B ( θ ) is the area of the triangle, find lim θ 0 + A ( θ ) B ( θ ) y = sec θ tan y = sec θ tan θ y' = sec θ (sec 2 θ ) + tan θ (sec θ tan θ ) = sec θ (sec 2 θ + tan 2 θ ). 1 + tan 2 θ = sec sec θ (1 + 2 tan 2 θ ) or sec θ (2 sec 2 θ 1). 0 Solution or Explanation Click to View Solution 10. 1/1 points | Previous Answers Solution or Explanation Using the identity we can write alternative forms of the answer as 11. 1/1 points | Previous Answers SCalcET7 3.3.015. Differentiate. f ' ( x ) = Solution or Explanation Click to View Solution . lim θ 0 + A ( θ ) B ( θ ) y = sec θ tan y = sec θ tan θ y' = sec θ (sec 2 θ ) + tan θ (sec θ tan θ ) = sec θ (sec 2 θ + tan 2 θ ). 1 + tan 2 θ = sec sec θ (1 + 2 tan 2 θ ) or sec θ (2 sec 2 θ 1). θ 2 θ ,
