Differentiate implicitly on both sides with respect to x to get: 2=cos(y) • (dy/dx). Divide by cos(y) on both sides to get: dy/dx=2/cos(y). Use the trigonometric identity cos^2(y)+sin^2(y)=1 rearranged to...

As an action potential arrives at A (the presynaptic terminal), pre-formed vesicles containing a chemical neurotransmitter fuse with the presynaptic membrane, releasing the chemical neurotransmitter into ...

to find dy/dx, multiply each item by the power of the x, and then decrease the power of the x by 1.Step 1 : 2x^2 -15x (multiplying by power of x)Step 2 : 2x^1 -15x^0Therefore:dy/dx = 2x ...

To measure development it needs to be defined. The are different types of development - environmental, social, economic. It can be argued that development is impossible to measure, due to the fact that it...

Book twelve of the Aeneid, the final book of the epic, culminates in a final act which epitomises the relationship between furor (rage) and pietas (duty to family, gods and state) which has been central t...
