When approximating definite integrals using Simpson’s Rule, which aspect has no effect on determining its accuracy?
The choice between even or odd numbers for subintervals as long as they are sufficient in quantity
Decreasing width size between each distinct subinterval for more precision

The smoothness and behavior of the curve being approximated over that interval
What best explains why even though two functions may have derivatives bounded by same constant M their corresponding Taylor polynomials’ errors differ over same interval?
Each function’s convergence rate within chosen radius solely dictates error size.
The initial conditions of each function necessarily affect their errors' magnitude.
Different functions have varied higher-order derivatives affecting error.
Functions having identical Maclaurin expansions cannot yield different errors.

What is required for a sequence defined by to demonstrate conditional convergence?
There is no condition under which it can converge conditionally as the sequence diverges absolutely due to its constant ratio being greater than one in absolute value.
Conditional convergence would require that it passes Root Tests but fails Ratio Tests given alternating sign criteria.
It can only converge conditionally if passed through geometric series tests showing alternating signs between terms.
It must pass both Alternating Series Tests but fail Absolute Convergence.
Which of the following statements is true regarding the Lagrange Error Bound for a Taylor series approximation?
The error bound is only applicable to trigonometric functions.
The error bound varies depending on the degree of the polynomial.
The error bound is constant across all intervals.
The error bound depends on the value of the function at the interval endpoints.
Given the infinite series , what test would prove it diverges?
Ratio Test
Integral Test
Alternating Series Test
Root Test
