is the power series representation for the function f(x) = x³sin(x) + e³ˣ⁺². This can be obtained by using power series representation of each terms, sin x, eˣ and substituting in the function.
<h3>Find the power series representation for the function:</h3>
In the question the given function is,
⇒ f(x) = x³sin(x) + e³ˣ⁺²
We know that series representation of sin x and eˣ are:
⇒ 
= 
Substituting the series representation in the function we get,
⇒ f(x) = x³sin(x) + e³ˣ⁺²
⇒ 
Hence is the power series representation for the function f(x) = x³sin(x) + e³ˣ⁺².

The value of x
3x°+46°+(2x-1°)=180°(angle sum of △)
5x+45=180°
5x=180°-45
x=135÷5
x=27
x is 27
put x into angle B,we have
2(27)-1
=53
thus angleB is 53°
hope it helps c:
Answer:
2
Step-by-step explanation:
this is a 30-60-90 Δ and the ratio of the sides are 1 : 
: 2
1 / 2 = / x
cross-multiply: x = 2
