Question 1

What is a Taylor Series Calculator?

Accepted Answer

A Taylor series approximates any smooth function as an infinite polynomial around a point. Truncating it gives a polynomial approximation — the basis for how calculators compute sin, cos, and eˣ.

Question 2

How does the Taylor Series Calculator work?

Accepted Answer

f(x) ≈ f(a) + f'(a)(x−a) + f''(a)(x−a)²/2! + ... Then: sin(x) = x − x³/6 + x⁵/120 − ... Then: cos(x) = 1 − x²/2 + x⁴/24 − ... Then: eˣ = 1 + x + x²/2 + x³/6 + ....

Question 3

Can you give an example of how to use the Taylor Series Calculator?

Accepted Answer

Example: Input sin(0.5 rad) using 3 terms gives a result of 0.5 − 0.5³/6 + 0.5⁵/120 = 0.4794 (Exact: 0.47943; error < 0.0001).

Question 4

Is the Taylor Series Calculator free to use?

Accepted Answer
