Answer:
Step-by-step explanation:
We can first solve for the face diagonal. That is . Notice this will form a right triangle with the vertical side. We get that the face diagonal =
. Now, we can use Pythagorean theorem again to get the straw length:
where s = the straw length.
We can solve that s =
#2) Use quotient rule
Remember for solving log equations:
#3) Derivative of tan = sec^2 = 1/cos^2
Domain of tan is [-pi/2, pi/2], only consider x values in that domain.
#4 Use Quotient rule
#9 Use double angle identity for tan
This way you can rewrite tan(pi/2) in terms of tan(pi/4).
Next use L'hopitals rule, which says the limit of indeterminate form(0/0) equals limit of quotient of derivatives of top/bottom of fraction.
Take derivative of both top part and bottom part separately, then reevaluate the limit. <span />
