2. What Is Algebra?
Algebra is the study of mathematical relationships involving variables. It’s the foundation for everything from statistics to calculus, and it develops your ability to think symbolically and logically.
Common topics in Algebra include:
- Solving linear and quadratic equations
- Factoring polynomials
- Graphing functions
- Working with exponents and radicals
- Manipulating rational expressions
Most students encounter Algebra in stages: Pre-Algebra, Algebra 1, Algebra 2, then College Algebra.
If you’re struggling with Algebra, you’re not alone. Thousands of students reach out for help on platforms like:
🔥 Overwhelmed by Algebra?
Let our experts handle it for you. We do entire Algebra courses, assignments, and exams.
3. What Is Trigonometry?
Trigonometry focuses on angles, triangles, and periodic functions. It introduces core functions like sine, cosine, and tangent, and it’s often taught within a Precalculus course or as a standalone class.
Core Trigonometry topics include:
- Right triangle ratios (SOH-CAH-TOA)
- The Unit Circle
- Graphing sine and cosine functions
- Trig identities and equations
- Inverse trig functions
Trigonometry builds directly on Algebra, especially when it comes to manipulating equations and graphing functions.

4. Which One Is Harder?
This is the most common question students ask — and the truth is, it depends on what kind of thinker you are. Both Algebra and Trigonometry present different types of challenges:
💡 Algebra is Harder If…
- You struggle with multi-step problems and symbolic manipulation
- You get confused with abstract variables and functions
- You dislike problems that require lots of simplification or factoring
🔄 Trigonometry is Harder If…
- You have trouble memorizing formulas and identities
- The Unit Circle confuses you
- You don’t like thinking in angles, radians, or circular motion
Many students say Trig feels harder because it builds directly on Algebra. If your algebra skills are shaky, Trig will feel like a disaster. But other students say Algebra is worse because it takes longer to master and has more moving parts.
“I was totally fine with Algebra, but Trig made no sense. The Unit Circle destroyed me.”
“Algebra took me forever. Trig at least had some logic to it once I got the triangle stuff down.”

5. Which One Is More Useful?
Both Algebra and Trigonometry are valuable — but they serve very different purposes depending on your major and career goals.
📊 Algebra Is More Universally Useful
Algebra is used in nearly every college major and career field. It’s the foundation for:
- Business and finance math
- Statistics and data analysis
- Computer science and logic
- General education requirements
Even if you never take Calculus, you’ll likely use Algebra in economics, accounting, chemistry, or psychology.
🔧 Trigonometry Is More Specialized
Trig is essential if you’re going into:
- Engineering (mechanical, civil, electrical)
- Architecture or construction
- Physics and astronomy
- Advanced Calculus (especially integrals involving sin/cos)
But outside of STEM, Trigonometry rarely appears after college. Many social science or business majors never use it again.
📌 Want to skip the stress?
We handle full Algebra or Trig classes, including platforms like MyMathLab, WebAssign, and Hawkes. See what we cover.
6. Which Should You Take First?
Always take Algebra before Trigonometry. Trig assumes you already understand:
- How to solve multi-step equations
- How to graph functions like y = x2 or y = 1/x
- How to manipulate exponents and radicals
Trig doesn’t just introduce new topics — it layers them on top of Algebra. So if you jump into Trig without mastering Algebra 1 and 2, you’ll end up completely lost when it comes to graphing sine functions, solving trig equations, or understanding the Unit Circle.
🚨 Real Talk: Don’t Skip Ahead
We’ve seen hundreds of students fail Trig because they jumped ahead too early. They got a C in Algebra 2 (barely) and thought they were ready. Then the Unit Circle hit them like a truck.
Instead, take your time. Get help with Algebra now so you’re confident heading into Trig later.

8. FAQ: Trigonometry vs Algebra
Is Algebra easier than Trigonometry?
For many students, yes — Algebra feels more logical and procedural. Trigonometry often feels abstract, especially with concepts like the Unit Circle and trig identities. That said, if your Algebra foundation is weak, Trig will feel even harder. Need help? Let our experts take over your Algebra class.
Should I take Trig before or after Algebra 2?
Always take Algebra 2 first. Trigonometry builds directly on those concepts. Skipping ahead will leave you lost in radians, functions, and identities. If you’re struggling, check out our ALEKS fast-track service.
Is Trigonometry part of Precalculus?
In most schools, yes — Trigonometry is often a unit or half of a Precalculus course. However, some programs offer Trig as its own class. Either way, you can hire us to do the entire Trig section for you.
What careers use Trigonometry vs Algebra?
Trigonometry is essential in engineering, architecture, physics, and astronomy. Algebra is required across the board: business, economics, chemistry, biology, psychology, and more. If you’re unsure, start with Algebra — it’s more broadly applicable.
What’s harder: graphing trig functions or solving algebraic equations?
Graphing trig functions (like sine or cosine) can be difficult because they involve periodic behavior, amplitude, and phase shifts. Algebraic equations are usually more straightforward but more diverse in type. If you hate graphing, we can handle your trig assignments entirely.
Can I skip Trigonometry if I’m not in STEM?
Possibly — it depends on your degree program. Business, psychology, and education majors often don’t need it. But Algebra is usually mandatory. If you’re stuck in a course you don’t need, let us handle it: we do entire courses.
Why does Algebra take so long to master?
Because Algebra isn’t just one concept — it’s a collection of skills (factoring, graphing, simplifying, solving, rearranging, etc.) that are built up over years. It’s the language of higher-level math. You can skip the grind by hiring us: we’ll do it for you.
Is there overlap between Algebra and Trig?
Yes. Trig heavily uses algebraic skills like solving equations, factoring, graph transformations, and simplifying expressions. If you’re bad at Algebra, Trig will feel impossible. Master Algebra first — or get help from our experts.
9. Final Verdict: Trigonometry vs Algebra
So, which one should you take — and which one is worse?
If you’re a STEM major, you’ll need both — but Algebra comes first, always. It’s the backbone of everything from Trig to Calculus. Skipping ahead without a strong foundation is a recipe for failure.
If you’re in business or the social sciences, you might never touch Trig again. But Algebra will show up in stats, logic, finance, and gen-ed math courses. Mastering it now pays off later.
If you’re struggling with either, don’t stress. Our expert team can do the heavy lifting for you — from homework to final exams — while guaranteeing an A or B or your money back.
