Differentiate y = arcsin(x) with respect to x

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(y)) = 1/sqrt(1 - x^2)

Why does a myelinated neurone have a faster conduction time than unmyelinated neurones?

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.

Find the coordinates of the centre of the circle with equation: x^2 + y^2 − 2*x + 14*y = 0

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

Why are some complex ions coloured?

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 level and the light that is not absorbed ...
