Dear all

Exam 1 will take place next Monday 2/2.

It covers all the homework assignments past due, including today’s assignment.

The exam problems will be variations of the homework problems. So, please review all homework problems again.

If you have any questions, please ask tomorrow in class.

Calculus 3- Winter 2015

Feedback for HW Due 1/21

Approximately 3 problems will be graded each week. The more problems you try, the higher the chances you will have solved the selected 3.

Section 11.6, Problems 4, 12, 14, 18, 28, 44, 46,

Section 11.7, The following problem not from the book:

Find the cross-section of the following surfaces with the indicated planes. Determine what type the surface is, e.g. ellipsoid, paraboloid etc., and what type the cross-section is, e.g. ellipse, hyperbola, etc.

Quadric Surface Planes

x^2/3^2+y^2/4^2+z^2/5^2=1 x=2; y=3; z=4 (3 different planes; 3 different cross-sections)

x^2/3^2+y^2/4^2-z^2/5^2=1 x=2; y=3; z=4

x^2/3^2-y^2/4^2-z^2/5^2=1 x=6; y=3; z=4

z^2=x^2/3^2+y^2/4^2 x=2; y=3; z=4

z=x^2/3^2+y^2/4^2 x=2; y=3; z=4

z=x^2/3^2-y^2/4^2 x=2; y=3; z=4

x^2/3^2+y^2/4^2=0 x=2; y=3; z=4

Section 11.8, Problems 2(a),(b), 4(a),(b), 6(a),(b), 8(a),(b), 10(a),(b), 12(a),(b), 20, 22, 28, 40

Section 11.1, Problems 12, 34, 38

Section 11.2, Problem 24

Section 11.3, Problems 2, 8, 24 (the vector component of v along b is what we called the projection of v on b; you do not have to sketch the vector), 26

Section 11.4, Problems 4, 10, 12,

Section 11.5, Problems 4 (just the equation of the line, not the line segment), 8, 16, 26, 30, 32.

IN OUR OWN VOICE A National Alliance on Mental Illness Signature Program Monday, February 9, 2015 5:30-8:30PM Ford Life Sciences Room 113 In Our Own Voice (IOOV) is a unique public education program developed by NAMI (National Alliance on Mental Illness), in which two trained speakers share compelling personal stories about living with mental illness and achieving recovery. The speakers take their audience on a journey discussing their dark days, acceptance, treatment, coping skills and successes, hopes and dreams. IOOV is an opportunity for those who have struggled with mental illness to gain confidence and share their individual experiences of recovery while raising awareness and reducing stigma in their communities. IOOV presentations are given to individuals who are dealing with a mental illness, students, law enforcement officials, educators, providers, faith community members, politicians, professionals, inmates, and any interested civic groups. Our Speakers this year are: Kristen Famiano was diagnosed with Bipolar Disorder in 2003 at the age of 29 and prides herself in being honest and open about her successes and setbacks in recovery. She was featured in the January 2013 issue of Woman's Day magazine in an article titled, "We are Living Proudly with Bipolar Disorder." Kristen works as a counselor at Romeo High School and is a proud participant in the Prechter Longitudinal Study of Bipolar Disorder. Kristen is a Past President of Depression and Bipolar Support Alliance (DBSA) Metro Detroit and is a current support group leader. John Lynn grew up in Royal Oak and graduated from Michigan State University with a degree in Advertising. He has dealt with mental illness most of his life. His mom was hospitalized for mental illness several times for months at a time when he was growing up and had a profound impact on his life. Shortly after graduating from MSU, John experienced a couple of hospitalizations and was diagnosed with Manic Depression, now known as Bipolar Disorder. He has been hospital-free for 26 ½ years and leads a full life. He has been married for over 20 years and has two children. He works as a peer support specialist in supported employment. He also works a community health education instructor, teaching a class for expectant fathers. John is an active member of Toastmasters International and NAMI Metro, where he is an IOOV speaker and state trainer. He shares his personal experience to inspire and educate others on mental illness, recovery and stigma. The presentation is free of charge. Participants will be provided verification of attendance which may be used to confirm attendance for a course encouraging and supporting this learning event. Faculty are encouraged to support attendance at this unique learning opportunity for students enrolled in their courses Questions may be directed to MSON faculty: Katherine Marshall @ marshaka@udmercy Andrea Kwasky @ kwasyan@udmercy.edu Katherine A.

Dear all,

There will be no class today.

Instead, I want you to graph the following equations using wolframalpha.com

**2-D**

(a) x^2/3^2 + y^2/4^2=1

What shape is the graph? What are the x- and y- intercepts?

(b) x^2/3^2 – y^2/4^2=1

What shape is the graph? What are the x- and y- intercepts?

**3-D**

(c) x^2/3^2 + y^2/4^2 + z^2/5^2=1

This is called a ellipsoid?

What are the x- and y- and z- intercepts?

(d) x^2/3^2 + y^2/4^2 – z^2/5^2=1

This is called an ellipsoid of one sheet.

What are the x- and y- and z- intercepts?

(e) x^2/3^2 – y^2/4^2 – z^2/5^2=1

This is called an ellipsoid of two sheets.

What are the x- and y- and z- intercepts?

(f) z^2= x^2/3^2 + y^2/4^2

This is called an elliptic cone.

What are the x- and y- and z- intercepts?

(g) z= x^2/3^2 + y^2/4^2

This is called an elliptic paraboloid.

What are the x- and y- and z- intercepts?

(h) z^2= x^2/3^2 – y^2/4^2

This is called a hyperbolic paraboloid.

What are the x- and y- and z- intercepts?

Please print the graphs and submit together with your answers in class on Wednesday.
