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
What kinds of probability questions can AskSia answer?
AskSia answers the standard college and high school probability questions: sample space and event counting, addition rule, multiplication rule with independence checking, conditional probability and Bayes' theorem, expected value of a random variable, variance and standard deviation, and probability computations using binomial, normal, Poisson, geometric, exponential, and uniform distributions. Each question gets the right structure identified, the formula applied with values, and a plain-English interpretation of the result.

Step 02
AskSia picks the method.
Based on the problem structure, AskSia chooses the cleanest solution path and labels each step with the operation performed.
1
Set curves equal
x² = 2x → x = 0, x = 2
2
Set up the integral
A = ∫₀² (2x - x²) dx
3
Evaluate
A = [x² - x³/3]₀² = 4/3
Step 03
Read the verified answer.
Final result appears with a substitution or composition check. Practice problems on the same concept are one tap away.

FAQ
Frequently asked questions.
What is expected value?
Expected value of a random variable X is the long-run average value of X over many trials. For a discrete X, it equals the sum of x times P(X equals x) over all possible values x. For a continuous X, it equals the integral of x times the density. Expected value can be in dollars, points, or any other unit, which AskSia preserves.
How is variance of a random variable computed?
Variance equals expected value of (X minus mu) squared, equivalently expected value of X squared minus mu squared. For a discrete X, it equals the sum of (x minus mu) squared times P(X equals x). AskSia computes the expected value first, then the variance, then the standard deviation (square root of variance) if needed.
When do I use the binomial distribution versus the Poisson?
Binomial: fixed number of trials n, each independent with probability p of success, count the number of successes. Poisson: count of events in a fixed time or space interval at constant average rate lambda. They are related: binomial is approximately Poisson when n is large and p is small. AskSia picks based on the problem structure.
Can AskSia handle Bayesian updating?
Yes. Bayes' theorem is the fundamental update rule. AskSia applies it to disease testing problems, quality inspection, drug efficacy, and any setup where you know the likelihood and the priors. AskSia displays the full numerator and denominator for transparency.
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.
