Chapter 6.5, Problem 14E

Advanced Math

green. A golfer makes a successful chip shot to the Suppose the path of the ball from the moment it is struck to the moment it hits the green is described by y = 13.51 x -0.62x² where * { [0,b]. where x is the horizontal distance (in yards) from the point where the ball was struck, and y is the vertical distance (in yards) above the fairway. a.) set up the integral (to just before integrating) to find the distance the ball travels (the arc length) from the moment it is Struck to the moment it hits the green. b.) If the ball travels 42 yards Chorizontally) down the fairway, find the arc length the ball travels. Round the nearest hundred.

What is the integral? I completed the square and set t-3=sqrt(2)sec(theta). Everything (including dt) would cancel out, leaving the integral of tan(theta), which would become ln|sec(theta)|+C, but my actual value of sec(theta) is either wrong, or the process leading up to this is wrong.

(ii) Evaluate the definite integral r³e² dr.

How does one do 14?

Evaluate the integral sec(theta)/sec(theta)-tan(theta) d(theta) A. sec2(theta) - tan(theta) + CB. tan(theta) + sec(theta) + CC. tan2(theta) + sec(theta) + C D. tan (theta) - sec(theta) +C please let me know if you need a picture. I wish i was able to format the integral better here.  sec(x)/sec(x)-tan(x) dx (this is to help if you don't understand the theta input)
