What mode should a calculator be in for calculus operations, especially when using trigonometric functions?

• Degrees

• Radians

• Gradians

• Polar

Which formula correctly represents the average rate of change of a function f(x) over the interval [a, b]?

• (f(b) - f(a)) / (b - a)

• (f(a) - f(b)) / (b - a)

• (b - a) / (f(b) - f(a))

• (f(b) + f(a)) / 2

What is the consequence of rounding early in calculations?

• It leads to a more precise final answer.

• It helps simplify complex calculations.

• It can throw off the final answer and lead to imprecision.

• It is a recommended practice for quick estimations.
