Algebra -- Trig -- Writer's Note: The symbol "n" should really be referred to as "pi" or "?" To prevent confusion within the problem. Also, there is a difference between "squared" and "square root." The case in these problems is to use the square root, so "sqrt (number)." I've only managed the calculations because I have presumed the indicated changes.

Using the periodic properties of trigonometric functions, find the exact value of the expression

cos-

cos (8?/5) = cos (2? + (2?/5)) = cos (2?/5) = cos (72) = 0.31

cos (8?/5) = 0.31.

The point P. On the unit circle that corresponds to a real number t is:

{ 5-2 6 squared}

} Find csc (t)

P is on the unit circle, therefore the coordinates are (cos (t), sin (t)). This leads to the following calculations:

sin (t) = -2sqrt (6)/7, and csc (t) = 1/sin (t) = 1/(-2sqrt (6)/7) = 7/(-2sqrt (6)) = -7/2sqrt (6)

Answer:...

The point P. On the unit circle that corresponds to a real number t is:
{ 7 squared 3 }

{ - -, -- } Find the cot (t)

{ 4-4 }

P is on the unit circle, therefore coordinates are (cos (t), sin (t)). This leads to the following calculations:

cot (t) = cos (t)/sin (t) = x/y cos (t) = -sqrt (7)/4, sin (t) = -3/4

cot (t) = [-sqrt (7)/4] / (-3/4) = sqrt (7)/3

Answer: cot (t) = sqrt (7)/3.

5. What is the domain of the sine function?

Answer: The sine function is a continuous function along the x-axis, therefore the domain is all real numbers.

6. Find the reference angle for the…

Algebra, Trig Algebra-Trig Find the slope of the line that goes through the following points: (-4, 6), (-8, 6) Slope: m = (y2 -- y1) / (x2 -- x1) = (6 -- 6) / (-8 -- (-4)) = 0 / (-4) = 0 m = 0. Determine whether the given function is even, odd or neither: f (x) = 5x^2 + x^ To test a function for even, odd, or neither property, plug in -- x

6. The rabbits will never die. The question was how many male/female rabbit pairs will be there after a year or 12 months? When the experiment begun, there is a single pair of rabbits. After duration of one month, the two rabbits have mated though they have not given birth. As a result; there is still only a single pair of rabbits. After duration of two months, the initial pair of rabbits will give

Who would you most like to invite? That is very difficult, since I just started reading about all the people who are doing wonderful things today around the world. I know I want to meet someone about astronomy and also computers. Thank you for your interview. Do you have any last words? Only that no one should give up on their interests because they feel lesser of a man from someone else.

ADD/ADHD Attention Deficit Disorder (ADD) and Attention Deficit Hyperactivity Disorder (ADHD) are both behavioral illnesses that are affecting a growing number of children and teenagers. Currently, more boys than girls are diagnosed with ADHD. A number of adults are also being diagnosed with adult-onset ADHD. Furthermore, an estimated one-third of children diagnosed with ADHD will continue to have symptoms until adulthood (Weyandt et al. 2003). Through greater exposure in the media and

Ferguson's Argument and Evidence In Eugene Ferguson Engineering and the Mind's Eye, he makes the case that the existing privileging of science and math over the nonverbal and visual in engineering education is mutually a dangerous practice and a historical abnormality. By applying a well-demonstrated chronicle of engineering strategy, Ferguson claims that not all engineering complications can be resolved by analysis in mathematical; short of the ability to envisage machines, environment,

Sunmee Choi & Anna S. Mattila (Cornell Hotel & Restaurant Administration Quarterly): The impact that a hotel can have on customers by sharing a frank and specific list of pricing practices ("revenue management" [RM]) is significant, according to a peer-reviewed journal article published in 2005. Choi & Mattila conducted a study of 120 travelers (all waiting for flights from Reagan National Airport in Washington, D.C.), providing them with three distinctly
