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 does AskSia analyze circuits?
By applying Kirchhoff's current law (KCL: currents into a node sum to zero) and Kirchhoff's voltage law (KVL: voltages around a loop sum to zero), combined with Ohm's law for resistors and the constitutive laws for other components (capacitors and inductors). For complex circuits, mesh analysis assigns currents to loops, and nodal analysis assigns voltages to nodes; either reduces to a linear system. For AC steady-state, AskSia uses impedance and phasors instead of resistance.

FAQ
Frequently asked questions.
What is Kirchhoff's current law?
KCL: at any node in a circuit, the algebraic sum of currents flowing into the node equals zero. Equivalently, currents in equal currents out. KCL follows from charge conservation: charge does not accumulate at a node, so what flows in must flow out. AskSia uses KCL at each node to write current equations in nodal analysis.
What is Kirchhoff's voltage law?
KVL: around any closed loop in a circuit, the algebraic sum of voltage drops (and rises) equals zero. Equivalently, the total voltage around a loop is zero. KVL follows from energy conservation: a charge that traverses a loop returns to its starting point with the same energy. AskSia uses KVL around each independent loop in mesh analysis.
How does mesh analysis work?
Assign a current to each independent mesh (loop) in the circuit. Apply KVL around each mesh, expressing voltages across each element in terms of the mesh currents. The result is a linear system: one equation per mesh, one variable (mesh current) per mesh. Solve the system to find mesh currents, then compute element currents and voltages.
What is a Thevenin equivalent?
Any linear two-terminal network can be replaced by a Thevenin equivalent: a voltage source (open-circuit voltage at the terminals) in series with a resistance (Thevenin resistance, computed with sources turned off). From the load's perspective, the Thevenin equivalent behaves identically to the original network.
How accurate is AskSia?
AskSia hits 98% accuracy on standard high school and college coursework, measurably higher than ChatGPT, Photomath, and Symbolab on the same problem sets. 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.
