Homework Statement Which of the below vectors are A). Orthogonal B.) in the same direction C). in opposite directions Homework Equations Vectors: u1 = (1,2) u2 = (0,1) u3 = (-2,-4) u4 = (-2,1) u5 = (2,4) u6 = (-6,3) The Attempt at a Solution The text told me how to find if two...

Homework Statement Use a CAS and knowledge of level curves to plot representative graphs of the members of the family of solutions of the differential equation. Experiment with different numbers of level curves as well as various rectanguar regions defined by a<x<b,c<y<d. Then on separate...

Well, cruds. Thank you! I'm off to find another problem then I guess. They did say I could also choose arc lengths. Maybe I'll go with that...

So One of the Integration Techniques can't be used, then?

Homework Statement Hey everyone. In my calc course I need to create (or find on the web) a problem and apply the below two concepts that I learned in the class. Concepts: Solids of Revolution. Integration Techniques: Parts, Substitution, or Partial Fractions. Homework Equations The problem...

Hey everyone, I hope this is the right place to put this. I was wondering if you could answer this question. Basically, I'm having trouble with my Numerical Methods course. The only college-level math course I took before this was the Calculus 1 course. I'm wondering if because I hadn't yet...

Oop... edited question to make more sense. :)

Homework Statement Find the Taylor Polynomial T2(x) (degree 2) for f(x) expanded about X0. f(x)=3x + cos(3x) X0= 0 Find the error formula and then find the actual (absolute) error using T2(0.6) to approx. f(0.6). The Attempt at a Solution As I've said on this forum before...

Okay so I somehow got -4.25. Does anyone else think that is correct? Anyone know how to find the actual error?

Yep, you are right. ln(x). Sorry about that. :) Thanks so much!

Hey guys! I am attempting to do this problem and have been working with it for awhile now. Once again, it is an issue of the textbook not being very clear and making me more confused than ever. Sadly, our teacher is still MIA. Find the third Taylor polynomial P3(x) for the function f(x)=...

Homework Statement Hey everyone! I was handed this question in class without being taught how to do it! The text is supposed to be helpful but it is just confusing. Using Gaussian elimination and 3-digit rounding arithmetic, solve the following linear system: 3.3330x_1 +15920x_2...
