Exercise 2.1a. Sketch (by hand, without using MATLAB) the direction field of the differential equation dy⁄dx= y⁄5for xand yvalues between -5 and 5. (You do not need to include this sketch in your write-up.)b. On your direction field, add a curve (by hand) that approximates the solution passing through the point x = 0, y = 1.c. Now solve the differential equation given in part (a), either working it out by hand or using the dsolve command that we saw in Assignment 1. Compare your answers to parts (a) and (b)

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

no

explanation:

you can be freinds, and people but not follow people.

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
