I can't figure out this one geometry/calculus question on one of the Calculator tests and its bugging me! Its the TMSCA state test # 59. They basically show the area under the curve from x=1 to x=5 is 4, and the equation of the curve is y= (cos(1/x)) / (Ax^2). They ask us to find the value of A. So I know that basically we know the definite integral of the equation from 1 to 5 is 4, so we just need to integrate and solve for A but im not sure how to do that? Would we do integration by parts or what? please help!!
