y = arcsin(x) implies sin(y) = x
Differentiating with respect to x gives: cos(y)*dy/dx = 1So: dy/dx = 1/cos(y)
Noting that cos(y) = sqrt(1 - sin^2(y)): dy/dx = 1/sqrt(1 - sin^2...

Myelination allows saltatory conduction to occur, which is when the impulse 'jumps' along the axon using the nodes of Ranvier. The myelin also acts as an electrical insulator.

method: complete the squares for (x^2 - 2x ) and ( y^2 + 14y ) using the formula (b/2)^2 (where the general equation is ax^2 + bx) so that the equation becomes ax^2 + bx ...

Note: sqrt means square root, and * means multiply method (overall aim is to make x the subject): multiply both sides by sqrt(5) to get: 15 * sqrt(x) = 6 * 5further expand the right hand sid...

Ligands causes d orbitals to split. Electrons get excited to higher energy levels from ground state. Visible light is absorbed to promote electron to a higher energy leve...
