### Question of the Day: Calculus 3

Determine whether the two vectors, and , are orthogonal or not.

The two vectors are *not* orthogonal.

The two vectors are orthogonal.

Calculus 3 revolves around complex concepts extending into multivariable calculus. Many previous familiar operators become multidimensional, flexible, and viable for numerous situations. Students need to have a deep understanding of the concepts behind what each operator does, and how it can transform functionally. If you feel that you need extra help extending concepts to 3D, or further, you may benefit from Varsity Tutors’ Learning Tools. While the course is not a mandatory mathematical one, if you are interested in expanding your knowledge of calculus into higher dimensions, you will need specific tools geared towards optimizing your studies and knowledge, like the Question of the Day. Whether you need Calculus tutoring in Atlanta, Calculus tutoring in Houston, or Calculus tutoring in San Francisco, working one-on-one with an expert may be just the boost your studies need.

Calculus 3 deals with familiar concepts; however, there are also concepts that will be new to you. You will be integrating multiple variable functions into a single area, thinking in terms of spatial integration, and going beyond the formulaic equations. The ideas can be intriguing, but difficult if you aren’t confident in your skills. You can, however, work to improve your skills through daily Calculus 3 practice with the Learning Tools. The Question of the Day provides you with the chance to take a swing at a random Calculus 3 concept once a day. When you answer, you are given a plethora of information that details your percentile, an explanation behind the answer, and a link to a better explanation of the core concept. Varsity Tutors offers resources like free Calculus 3 Practice Tests to help with your self-paced study, or you may want to consider an Calculus 3 tutor.

The Question of the Day is chosen from the free Calculus 3 practice tests, which are designed to mimic the real tests you may have to take. These questions cover every type of Calculus concept that you may need to know for final exams, as well as for testing along the way. You may get a question on the arc length and curvature of 3-D space, or spherical coordinates, lines and planes equations, and cylindrical coordinates. Other core concepts include tangent planes and linear approximations, Lagrange multipliers, absolute minimums and maximums, integration and derivatives, line integrals, Fundamental Theorem of Line Integrals, Green’s Theorem, double and triple integrals, partial derivatives, surface integrals, vectors, vector operations, Stokes’ Theorem, and Divergence Theorem.

By answering this question, you are able to get additional test review practice each day. However, you don’t have to stop there! You can further access Learning Tools that are geared towards promoting your knowledge of Calculus 3. Flashcards provide a quick review-style study session, and can be used for competitive study games. The full-length practice tests offer realistic practice to help familiarize yourself with the test. Learn by Concept provides a breakdown of each concept into smaller concepts that work together to provide a basis for the base concepts. In addition to the Calculus 3 Question of the Day and Calculus 3 tutoring, you may also want to consider taking some of our Calculus 3 Flashcards.

If you need extra Calculus 3 help, you can use the free material provided by Varsity Tutors’ Learning Tools. You can access the Question of the Day from your smartphone, tablet, or computer for a quick review on the go. By pairing the review help with your ongoing schoolwork, you can enhance your learning. Consider combining different tools to form your own study plan!
