Hi,

I am really struggling to solve this differential using the basic rules that I know.

There should be a dot above the A in the numerator on the left hand sideand brackets around the fraction on the right hand sidebut I wasn't sure how to do that.

Any help gratefully received!!

Imagine a country that is adopting foreign technologyT as shown in the following equation where$\displaystyle \frac{A}{A}= \phi(E)\frac{T(t)- A(t)}{A(t)}$A denotes the level of domestic technology and the dot overA denotes its derivative with respect to time:

a) Assume that the level of foreign technology is constant and solve the differential equation above

b) What is the effect of an increase in the level of educationE?

c) What is the effect of an increase in the rate of growth of foreign technology λ?
