With each of the problems include a basic sketch of the integrand function and shade the signed area represented by the integral.

1. Find ntegral from 2^4 t^3 dt.

2. Find ntegral from (-2)^2 x^4 dx.

3. Find ntegral from 2^(x) t dt(The answer is a function of http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bx%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15).

4. Find ntegral from (1)^e(1/z+1/[z^2])dz(= 2.71 dots).

5. Find ntegral from (0)^(pi) (cos z+z) dz.

6. For what http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bx%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15is the area under the graph of (t) = 1/tbetween = 1and = xequal to http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7B1%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15?

7. The chance that a specific type of FLC (compact fluorescent lamp) bulb burns out within auyears is given by

(tau) = integral from 0^tau e^(-t) dt.

Calculate the chance that a given bulb lasts at least 5 years.

8. (ask, discuss - and share your ideas, but no need to submit - a great opportunity to increase your participation). A unit disk is sliced so that the smaller portion has width http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bh%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15. How would you set up the integral? What is the picture? Since calculating this integral can be difficult as we did not cover substitution tricks, use wolframalpha to find the antiderivative.

9. (ask, discuss - and share your ideas, but no need to submit) The graph of a function http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bf%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15is sketched below. (a)Without finding an antiderivative of (x), calculate ntegral from 0^1 f(x) dx. (b) How would a graph of an antiderivative of (x)look like?
