# 1617-257/Homework Assignment 9

## Doing

Solve all the problems in sections 13-14, but submit only your solutions of problem 4 in section 13 and problems 4 and 8 in section 14. In addition, solve and submit your solution of the following problems:

Problem A. Compute the volume of the "2D ice cream cone", $C=\left\{(x,y)\colon |x|\leq y\leq 1+\sqrt{1-x^2}\right\}$.

Problem B. Compute the volume of the "n-dimensional simplex" $\Delta_n=\left\{(t_1,\ldots,t_n)\colon 0\leq t_1\leq t_2\leq\ldots\leq t_n\leq 1\right\}$.

## Submission

Here and everywhere, neatness counts!! You may be brilliant and you may mean just the right things, but if the teaching assistants will be having hard time deciphering your work they will give up and assume it is wrong.

This assignment is due in class on Wednesday November 30 by 2:10PM.

### Important
