## What is the series expansion of TANX?

Sequence of Terms The Power Series Expansion for Tangent Function begins: tanx=x+13×3+215×5+17315×7+622835×9+⋯

## How do you expand a Taylor point?

The expression for Taylor’s series given above may be described as the expansion of f(x+h) about the point x. It is also common to expand a function f(x) about the point x = 0. The resulting series is described as Maclaurin’s series: f(x) = f(0) + xf (0) + x2 2!

**How do you find the general formula for a Taylor series?**

ak and ak=3−k−1=1/3k+1, so the series is ∞∑n=0(x+2)n3n+1. Such a series is called the Taylor series for the function, and the general term has the form f(n)(a)n!

**What is the expansion of tan2x?**

tan2x = sin 2x/cos 2x.

### What is the expansion of E X?

ex=∑r=0r=∞r! x.

### How do you find the convergence of a Taylor series?

Based on this value of L, we can therefore determine for which values of x the original Taylor series converges.

- If L=0, then the Taylor series converges on (−\infty, \infty).
- If L is infinite, then the Taylor series converges only at x=a.

**What is the general expression for the nth term for the Taylor series?**

The general term of a Taylor polynomial or series is given by tn=fn(a)(x−a)nn!. The degree of a Taylor polynomial of a given polynomial shall be the same as the degree of the function itself. The Taylor expansion is an infinite series.

**What is the formula of tan AB?**

tan(A + B) = (sin A cos B + cos A sin B) / (cos A cos B − sin A sin B) (50) tan(A + B) = (tan A + tan B) / (1 − tan A tan B) Now if you replace B with −B, you have the formula for tan(A − B).

#### What is the formula of Cot2x?

Cot2x formula is an important formula in trigonometry. It is mathematically written as cot2x = (cot2x – 1)/(2cotx). Cot2x identity is also known as the double angle formula of the cotangent function in trigonometry….Cot2x.

#### What does e x mean in math?

Expected Value

In a probability distribution , the weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value , usually represented by E(x) .

**What is e in math terms?**

Euler’s Number ‘e’ is a numerical constant used in mathematical calculations. The value of e is 2.718281828459045…so on. Just like pi(π), e is also an irrational number. It is described basically under logarithm concepts. ‘e’ is a mathematical constant, which is basically the base of the natural logarithm.
