Yes, you need to use the chain rule. Also you need to use the derivative of arcsin which is in tables.
Derivative of y = arcsin(x) = 1 / [√(1 - x^2)]
Chain rule: Derivative of archsin(cos(2x)) =
y' = 1 / [√(1 - (cos(2x))^2)] * derivative (cos(2x) =
y' = 1 / [√(1 - (cos(2x))^2)] * (- sin (2x)) * 2
y' = -2(sin(2x)) / [√( 1 - (cos(2x))^2]
Answer:
2.828 km
Explanation:
radius of lake, r = 2 km
Let O be the centre of the circular lake and you walk from A to A to D.
Displacement is the measure of shortest distance between two points.
According to the diagram , the displacement AD is
(By using the Pythagorean theorem)
AD = 2.828 km
thus, the displacement is 2.828 km.

Answer:
Resonance structures have <u> </u><u>same</u><u> </u> connectivity of atoms and <u> differ only in</u> distribution of electrons.
Explanation:
Atoms supply the electrons from their outer electron shells. Electrons are found free in nature and are grouped around the nucleus into shells. Electrons can be further explained as negatively charged subatomic particle. Electrons have properties of both particles and waves and they can be moved around.
Resonance structures are imaginary structures and not all of them are created equally. Resonance structures have two or more possible electron structures, and, the resonance structures for a particular substance sometimes have different energy and stability. When resonance structures are identical, they are important descriptions of the molecule. The position of the atoms is the same in the various resonance structures of a compound, but the electrons are distributed differently around the structure.
