Edexcel A-Level - June 2022 - Pure Maths Paper 1 - Question 16 - Exam Paper Walkthrough

Full walkthrough answer to Question 16 on the Edexcel A-Level Mathematics, Pure Maths paper 1, June 2022. Figure 6 shows a sketch of the curve C with parametric equations x = 8 sin^2 t y = 2 sin 2t + 3 sin t The region R, shown shaded in Figure 6, is bounded by C, the x-axis and the line with equation x = 4. (a) Show that the area of R is given by integral (8 - 8 cos 4t + 48 sin^2 t cos t) dt (b) Hence, using algebraic integration, find the exact area of R. . . . #maths #pure #alevel #edexcel #walkthrough
