Jean Piaget was the one who came up with the <span>four stages of intellectual (or cognitive) development and these are sensorimotor, pre operational, concrete operational and formal operational. The state in which a child has developed object permanence by the end of the sensorimotor stage. Hope this answers your question.</span>
Answer:
kinetic energy
Explanation:
As an object falls from rest, its gravitational potential energy is converted to kinetic energy
The limit from 1 to 2 of the given antiderivative is; -0.19865
<h3>What is the Limit of the Integral?</h3>
We are given the antiderivative of f(x) as sin(1/(x² + 1)). Thus, to find the limit from 1 to 2, we will solve as;

⇒ (sin ¹/₅) - (sin ¹/₂)
⇒ 0.19866 - 0.47942
⇒ -0.19865
Complete Question is;
If sin(1/(x² + 1)) is an anti derivative for f(x), then what is the limit of f(x)dx from 1 to 2?
