Calculus IV Problem Set 1 Fall 1998 Due 8/31/98

1. [1 point] Find the value of  pi correct to 30 decimal places.
 
 
 
2. [1 point] Find the equation of the line tangent to f(x) = e-x sin x where x = 1.
 
 
 
3. [1 point] Find the value of the ugliest integral (your choice) from problems 9-60 in the chapter 7 review.
 
 
 
4. [1 point] Look at the graphs of y = sin2 x and y = sin 2x. Which one is the derivative of the other?
 
 
 
5. [1 point] Consider the surface f(x,y) = cos . The surface doesn't have just one high point, but lots of them -- describe (in comprehensible english) the set of points where f takes on global maximum values.
 
 
 
6.[1 point] You're a drop of water at the point (/3,0,1/2) on the surface z = cos x cos y. Where do you end up? Describe (in some reasonably precise way) the region from which other drops of water will tend toward the same spot.
 
 
 
7. [2 points] Get Mathematica to plot a sphere of radius 5 centered at the origin. Explain how
you did it (you might include a printed copy of your work if you think it will help).
 
 
 
8. [2 points] Consider the function f(n) = . Compute f(1), f(2), f(3), f(4), (at least) and describe the pattern.
 
 
 
9. [3 points] Do problem #70 from section 12.1. Explain clearly what different shapes are possible depending on the values of a and b.
 
 
 
10. [2 points] Find something Mathematica can't do.
