Master Algebra II: Key Concepts, Tips, and Real-World Applications

Calculators

👉 Also part of the Mathematics Calculators theme.

Get Comfortable with Algebra II

Algebra II can feel overwhelming—functions, graphs, trigonometry, complex numbers. But you don’t have to navigate it alone. We’ve developed a wide range of calculators to guide you through each step, check your answers, or even explain what’s happening.

Whether you're graphing a parabola, solving inequalities, or working through exponential growth, these tools are here to simplify the process.

Tools That Make the Hard Parts Less Frustrating

Trying to find the roots of a polynomial? Use the Polynomial Roots Calculator to break it down quickly. If you're dealing with complex roots, the Complex Roots Calculator can guide you through it, and the De Moivre’s Theorem Calculator helps convert polar forms when necessary.

When expressions become complicated, our Simplify Expressions Calculator is a lifesaver. You can also switch between forms with the Complex Number to Polar Form Calculator or go the Other way with the Polar Form to Complex Number Calculator.

A few more that come in handy:

You can also find zeros with—you guessed it—the Zeros Calculator. And if you're curious about how a graph starts or ends, the End Behaviour Calculator can show that too.

Graphs, Shapes, and Motion—Visual Maths Help

Graphs can tell a multitude of stories. To understand what they’re conveying, the Graphing Calculator is a solid starting point. Whether it's a line, curve, or circle, seeing the visual helps it click.

Trying to figure out parabolas or hyperbolas? The Parabola Calculator and Hyperbola Calculator are right there for that.

Need to delve deeper into shapes? Try:

Want to rotate a figure around a point? Use the Rotation Calculator—it handles the maths for you.

Trigonometry Doesn’t Have to Be a Struggle

Trigonometry can seem tricky at first, but it helps unlock many problems in Algebra II. Our Trigonometry Calculator covers a variety of common functions.

Need help with angles or side lengths? Try:

We also have specific calculators for each trig function—and their inverses:

Want to go beyond standard trigonometry? The Hyperbolic Sine Calculator and Inverse Hyperbolic Sine Calculator step into that territory.

Working with identities? The Trig Identities Calculator can help you confirm if your rearranged version is correct.

Crunching Numbers, Step by Step

Sometimes you’re solving equations. Other times, you’re checking if two functions work together. We’ve got tools to assist on both fronts.

You can also:

Want to know what happens when you plug one function into another? The Composite Function Calculator shows exactly how that works.

More Handy Helpers You Might Not Know About

A few calculators serve special roles—and they’re good to know if your homework or test review takes an unexpected turn.

For example:

If you're expanding something like $(x + y)^n$, the binomial expansion Calculator saves time. And if you're working with combinations, the Binomial Coefficient Calculator finds values like “10 choose 3.”

There’s also the Factorial Calculator for multiplying descending numbers—and the Diamond Problem Calculator, perfect for factoring practice.

Need to turn a messy expression into partial fractions? The Partial Fraction Decomposition Calculator can split them cleanly.

Want to brush up on adding or subtracting polynomials? We’ve got a calculator for that, too.

Give any of these calculators a try—they’re ready when you are.
