In AV math, which function is NOT typically included in scientific calculators used for calculations?

In the context of scientific calculators, the cosine function is indeed included. Scientific calculators are designed to handle a wide variety of mathematical functions, including trigonometric functions such as sine, cosine, and tangent. This makes them highly versatile for calculations in geometry, physics, and engineering, where angles and their properties are often involved.

The other functions mentioned, such as logarithms, reciprocals, and exponents, are also standard features on scientific calculators, as they are essential for performing a range of mathematical operations. Logarithms allow for the calculation of powers in a different format, reciprocals provide the ability to find the inverse of numbers, and exponent functions facilitate exponential calculations crucial in many scientific fields.

Therefore, since cosine is indeed typically included in the function set of a scientific calculator, the answer does not align with what is not included. Options like reciprocals, logs, and exponents are also standard functions, reinforcing that these calculators are equipped to handle complex mathematical operations.
