Document Summary
Problem 1 (20 points): a 300-gallon container is 2. 3 full of water containing 50 pounds of salt. At time t = 0 minutes, valves are turned on so pure water is added to the container at the rate of 3 gallons per minute. Dividing cos2 y from both sides yields y = x cos2 y y cos2 y. By doing this , we are missing those solutions such that cos2 y = 0, which are y = all n is an integer. Plug in the intial condition x = 0 and y = . The speci c solution is that tan y = x. Solution: check my notes of problem number 2 on oct. 16. Bonus question (10 points): find the rst four nonzero terms in taylor series for these functions. (you can check your course package for the elementary taylor series expansions. )
