The principal part of e3ex3+3e^{3}-e^{x^{3}+3} as x0x \rightarrow 0 is a. 1e31-e^{3} b. x3e3-\frac{x^{3}}{e^{3}} c. e3x3-e^{3} x^{3} d. e3x-e^{3} x
Solution by Steps
step 2
The Taylor series expansion of ex3+3e^{x^3+3} at x=0x=0 is given by e3e3x3e3x62e3x96+O(x11)e^3 - e^3 x^3 - \frac{e^3 x^6}{2} - \frac{e^3 x^9}{6} + O(x^{11})
step 3
The principal part of the series is the term with the lowest degree of xx that is not a constant. In this case, it is e3x3-e^3 x^3
C
Key Concept
Principal Part of a Series
Explanation
The principal part of a series is the term with the lowest degree of the variable that is not a constant, which represents the most significant part of the series as the variable approaches zero.
