Tangent line of f(x) = sec x @ (pi/3, 2)

Mathematics

Dmitry_Shevchenko [17]3 years ago
3 0
The derivitive of sec(x) is sec(x)tan(x)

find the slope at pi/3

sec(pi/3)=2
tan(pi/3)=√3

sec(x)tan(x) at x=pi/3 is 2√3

for slope=m and a point is (x1,y1)
the equation is
y-y1=m(x-x1)
slope=2√3
point=(pi/3,2)

equation is
y-2=2√3(x-pi/3)

Tim wants to boil rice on the stove. He needs to use exactly three gallons of water in a pot to boil the rice. Which method shou
MatroZZZ [7]

A. is obviously the most easiest one, as you just have to fill it up 3 times to get 3 gallons.

The next one to measure exactly 3 gallons of water is B), because:

1) the 100-gallon barrel is more than 1 gallon, and is much more harder than 3 gallons.

2) Each person's 'palm' can hold different amounts of water, and so it can vary by the size of the palm.

So IF it cannot be (A), then your next choice is (B), as you only need 768 teaspoons for each gallon.

But, you should report this problem to the teacher, since A is obviously the best choice
