We can find dz/dy using chain rule dz/dy=dz/du x du/dy (1) by defining u=3y^2+5 (since the exponent of e is a function of y we call this function u) and rewrite z=e^u. Then, we find dz/du=e^u (2) and du/d...

Anti-diuretic Hormone (ADH) is secreted from the hypothalamus in the brain. If more ADH is produced, it makes the collecting ducts in the nephron of the kidneys, more permeable to water. Therefore, less w...

This function is fraction so the easiest method is to use the quotient rule (though the product rule can be used). Recall the quotient rule dy/dx = [vu' - uv']/[v^2]Note, u and v refer to the numerator a...

This is a topic that is becoming increasingly popular in both written and speaking French examinations. The basis for the structure of the answer can often be reapplied to a variety of topics including ce...

An ionic bond is the transfer of electrons from one atom to another to obtain a stable outer shell. This only happens between a metal and a non metal. For example, magnesium would transfer 2 electrons to ...
