1 Test. Due 8/26

The two trial questions below must be answered correctly and clearly readably. You must keep trying until the graders accept your answer as clearly readable and correct. If not, you cannot continue in the class, because we will refuse to grade your submissions.

Put the answer to each question on a separate page.

You will then need to scan your answers to a pdf file, each question page on a separate page in the pdf. Then submit that pdf file to Canvas as the solution for this first assigment.

I am informed that many students succeed in creating clearly readable pdf files using their mobile phone with the cam scanner software. Consider making a scanner box. Make very sure there is plenty of light on the paper. Make each homework page cover the entire screen.

Whatever you use, the pdf of your work must be very clearly readable for the graders. But do not use excessive resolution or jpeg quality. Resolution should be about 150 to 200 dots per inch. Jpeg quality should be whatever is listed as medium to slighly higher quality. If you are not using a flatbed scanner, keep your camera horizontal above the horizontal homework page, make sure that there is plenty of light on the page, and make the letter size page fill the entire picture. Scan either to color or grey scale, never to black & white.
