lozanna [386]
\lim_{x \to  \pi /4}  \frac{tan x - 1}{x- \pi /4}  =  \frac{0}{0}
With L` Hospital`s Rule ( ( tan x ) ` = 1/ cos^2 x ) :
\lim_{x \to  \pi /4}  \frac{1}{cos ^{2} x} =  \\ = \frac{1}{cos ^{2} ( \pi /4)}  = \\  \frac{1}{1/2}   =  2

Carlita saw 5 times as many robins as cardinals while bird watching. She saw a total of 25 birds. How many more robins did she t
andrew-mc [135]
Carlita was either sipping the hot chocolate while she was out, or else
approximating the numbers.  The exact number she reported is not
possible.  To see why, I'll do it strictly by the math:

Robins  =  5 times
Cardinals  =  1 time

Total birds  =  6 times 

6 times  =  25 birds

Divide each side by 6 :   1 time  =  25/6  =  4-1/6 birds

Robins =  5 times  =  20-5/6 of them
Cardinals  =  1 time  =  4-1/6 of them

Total:  (20-5/6) + (4-1/6)  =  25 birds.

How many more robins than cardinals  = (20-5/6) - (4-1/6) = 16-2/3 more. 

The math works out fine.  But if the numbers she reported are true,
then some of what she saw was partial birds ... legs, or feathers,
things like that.  Eeeew.   I don't want to talk about it.
