Maclaurin Series Calculator
Find Maclaurin Series Expansions Instantly
This calculator computes the Maclaurin series expansion (special case of Taylor series at x=0) for common mathematical functions.
Supported Functions Include:
- sin(x), cos(x), tan(x)
- eˣ, aˣ
- ln(1+x)
- arcsin(x), arctan(x)
- (1+x)ᵏ (binomial series)
How to Use:
- Type your function (examples below)
- Select polynomial degree (3-10 recommended)
- Click “Expand”
- See the series + convergence radius
Example Inputs:
sin(x)
→ x – x³/6 + x⁵/120 – …e^x
→ 1 + x + x²/2 + x³/6 + …1/(1-x)
→ 1 + x + x² + x³ + … (for |x|<1)

Common Questions:
Q: What’s the difference between Taylor and Maclaurin series?
A: Maclaurin series are Taylor series centered at x=0.
Q: Why does my series stop at a certain term?
A: Higher-degree terms become negligible for approximation.
Q: Can I use this for multivariable functions?
A: This tool is for single-variable functions only.
Mathematical Note:
All expansions are computed using exact coefficients rather than decimal approximations for maximum precision. The calculator automatically determines the radius of convergence where applicable.
