A. 2 circles that have the same center have their radiuses respectively 5 nd 3 cm. From A which is a point of the big circle are constructet the tangents with the small circles and we mark the pint of tangent A and B. Let's mark D and E the points where these tangents touch the big circle. Find the distance of the center O from DE. (my answer is 1.4 cm but i just don't know if I am right)
B. f(x)= (1-x)^1/2 / x Find the limit when x goes to - infinity.
Thanks in advance!
