A few people have asked me for examples of questions from my calculus
exams that were done with/without calculators. Here are a few --
NO CALCULATOR ALLOWED
Integrate : x^3 ln x dx
sin x cos x dx
xe^x dx from 0 to 1
1/(x^2 + 1) dx from 0 to 1
Use Taylor series to find
lim (x->0) [ (SQRT(x+1) - 1)/x ]
CALCULATOR (TI-92) ALLOWED
Convergence of series : SUM [ n/(n+1) ]
SUM [ (-1/2)^n ]
Volume of revolution problem ...
Find total mass of ash from Mt. St. Helens eruption within 100 meters
given density of ash
d(r) = 2000/(1+r^2) kg/square meter r meters from center
Solve : dy/dx = x^2 y^2
This was not the entire exam, but these problems are representative.
