The Curve C shows parametric equations x = 4tant and y = 5((3)^1/2)(sin2t) , Point P is located at (4(3)^1/2, 15/2) Find dy/dx at P.

First I would find the value of t at Point P - I would equate the x equation to 4(3)^1/2 and the y equation to 15/2. This would give me (Px,Py). After this I would then find dy/dt, and dx/dx by differentiati...

Explain how an action potential is transmitted from one neurone to another at a synapse.

A good answer would start with a definition of a synapse ('the junction between two neurones') and then be formatted as bullet points or numbers for clarity and backed up with a diagram. Action potentia l ar...

Solve the simultaneous equations, x+y = 16, 5x -2y = 17

Multiply the first equation by 2 to obtain 2x+2y = 32,Then use the elimination technique and add the first equation into the second equation to get : 7x = 49 therefore divide by 7 to find x = 7 Sub this valu...

How do you know which chemicals are formed at the electrodes in the electrolysis of aqueous solutions?

In electrolysis, positive ions will be attracted to the negative cathode (the cat hode being negative can be remembered because cats are evil). However, in aqueous solutions there are 2 positive ions: the on...

Evaluate the integral ∫(sin3x)(cos3x)dx (C4 Integration)

First, we must recognise that the integral is written as a product of two functions which cannot be directly integrated, therefore a trigonometric identity must be used to express this a single function. Sin...
