Problem
Find the area enclosed between y = x² and y = 2x in the first quadrant.
1
Find the points of intersection
Set the curves equal: x² = 2x → x(x - 2) = 0, so x = 0 and x = 2.
2
Identify which curve is on top
On (0, 2), 2x > x², so y = 2x is the upper curve.
3
Set up the area integral
A = ∫₀² (2x - x²) dx
4
Integrate term-by-term
A = [ x² - x³/3 ]₀²
Final Answer
A = 4/3 sq. units
Quick Answer
How do you find eigenvectors?
An eigenvector of a matrix A with eigenvalue lambda is a non-zero vector v satisfying A times v equals lambda times v, or equivalently (A minus lambda times I) times v equals 0. To find eigenvectors for a given eigenvalue lambda, form the matrix A minus lambda times I, row-reduce it, and find the null space. The non-zero vectors in the null space are the eigenvectors corresponding to lambda. Each eigenspace is the set of all such vectors plus the zero vector.

FAQ
Frequently asked questions.
How many eigenvectors does each eigenvalue have?
Each eigenvalue has at least one eigenvector. The dimension of the eigenspace (geometric multiplicity) can be from 1 up to the algebraic multiplicity of the eigenvalue. So an eigenvalue with algebraic multiplicity 2 can have either 1 or 2 linearly independent eigenvectors. AskSia computes the full eigenspace basis.
Why are eigenvectors not unique?
Any non-zero scalar multiple of an eigenvector is also an eigenvector with the same eigenvalue: if A times v equals lambda times v, then A times (c times v) equals lambda times (c times v) for any non-zero scalar c. So eigenvectors come in scalar-multiple families. AskSia presents the simplest representative.
How do you find eigenvectors for a repeated eigenvalue?
Set up the homogeneous system and find the null space, just like for any eigenvalue. If the eigenvalue has algebraic multiplicity k, the eigenspace can have dimension 1, 2, ..., or k. AskSia row-reduces the matrix, identifies the free variables, and produces a basis of the null space.
What is the connection to diagonalization?
If a matrix A has n linearly independent eigenvectors, you can form a matrix P whose columns are these eigenvectors and a diagonal matrix D with the eigenvalues. Then A equals P times D times P inverse. Computing A to the n becomes easy. AskSia provides the full diagonalization on request.
How accurate is AskSia?
AskSia is engineered for accuracy on standard high school and college coursework. Accuracy comes from subject-specialized models, a symbolic verification pass that catches arithmetic errors, and a self-check step that re-derives the answer before showing it to you.
Can I get practice problems and flashcards?
Yes. After any solve, ask Sia to generate similar practice problems at SAT, ACT, AP, IB, or college difficulty, or build a flashcard set on the underlying concept in one tap. Useful for exam prep and spaced repetition before a quiz, midterm, or final.
How much does AskSia cost?
AskSia has a free plan that includes daily solves across all subjects. AskSia Pro and Super include unlimited solves, advanced subjects, the full AI tutor companion, exports, and priority response speed. See pricing for details.
