Good day, may you assist me with the attached question

Use the trapezoidal rule with n = 4 to calculate an approximate value for 2fnx J cr . (5) 1 3: Find the RMS value of y = 4255.in between x = 0 and x=2n1. (5) Given the area bounded by the curve y = 25in2 x and the J: - axis between x = 0 and x = 1r. Calculate 4.1 the area bounded. (4) 4.2 the volume of the solid of revolution if this area rotates around the x- axis. (6) TOTALMIJ 1. Determine the following integrals: 1.1 dx +9 (3) X 1.2 dx x*+9 (3) 1.3 (x2)(e2) dax by using integration by parts. (7) 1.4 ex sinh x dx by not using integration by parts. Show calculation steps and leave your answer in terms of e. (4) sec x 1.5 dx (3) 1 + tan x
