2. Use the fundamental theorem of calculus to compute the integral of over the interval . Does your answer make sense, given that the graph of is unbounded?
3. Use the fundamental theorem of calculus to compute the integral
.
4. Use the fundamental theorem of calculus to compute the integral
.
5. Use the fundamental theorem of calculus to compute the integral
.
6. Use the fundamental theorem of calculus to compute the integral
.
Solution |
---|
The antiderivative of sin(kx) = -1/k(cos(kx)).
[ -1/3(cos(3x)] - [ -1/3(cos(3(0)))] = -1/3 (cos3x) + 1/3 (1) = -1/3 (cos3x - 1) |
