How would a crime scene investigator use trigonometry?
Examples include:
validating the line of sight evidence of witnesses.
calculating the angle of a shot being fired and therefore the direction from which a shot was fired. If several shots were fired in a small time interval (so the shooter was more or less in the same place), the shot trajectories identify his/her location.
in the case of blunt instrument injury, calculating the angle of impact can give some indication of the relative heights of the victim and assailant.
What is value of sin of 5.834 degrees?
According to the scientific calculator on my computer, that would be 0.1016. I gave you 4 significant digits because you gave me the angle to 4 significant digits.
This should be fairly straight-forward. Let's see... we have: 60 Meter per Pole * 24 Poles per Minute = 1,440 Meters per Minute * 60 Minutes per Hour = 86,400 Meters per Hour / 1,000 Meters per Kilometer = 86.4 Kilometers per Hour (or approximately 53.7 MPH). Are we good?
the fortistat of isobars multiplied by 34.98 inches divided by the barometric pressure on venus +456 cubic meters is the answer
Write z equals 3i in abbreviated trigonometric form?
z = 3i
r=3
theta=taninverse(3/0)=undefine
as we know tan theta is undefine at 90 and 270....check through qustion ..their is + sign with imag part....its mean angle is 90
so we write it as
3(cos90 + isin90)
The origin and the development of statistics?
The earliest recorded use of statistics was in the 5th century BCE. The ancient Greeks were attempting to scale a wall, and determined the necessary height for their ladders by counting the bricks in the wall. Since that time, the science of statistics has expanded to include both the collection of the data and the mathematical analysis thereof.
Who is founder of trigonometry?
No one in particular because trigonometry has evolved over thousands of years with many ancient and modern mathematicians making their own discoveries and contributions to the subject.
What are the importance of spherical trigonometry in mathematics?
We live on a sphere. Calculating 'shortest' distance on the sphere is not a simple trig problem, you may need spherical trig.
How do solve sin 2 theta - square root of 3 theta- equals 0?
The only real solution is theta = 0
For theta < 0 square root of 3 theta is not defined.
For theta > 0, sin theta increases slower than 3*theta and so the sum is always negative.

How can you graph tan x in Microsoft Excel?
In the 1st column make a list of numbers, and in the 2nd column calculate the tangent of each value in the 1st column. Try entering 0.01 in A1 and =A1+0.01 in A2, then select A2:A942 and fill down. In B1 enter =tan(A1), then select B1:B942 and fill down. Next, select A1:B942, then insert a line graph. Adjust the Y axis range until it looks good.
Why is Hipparchus the father of trigonometry?
Because he was credited with working out the mathematics behind it.
How can improve math of class XI?
the only soluton is regular practice.Pravtice makaes a man perfect.First be thorough with the book uypu have been prescribed with then try out with references.
After 12 hours, the first boat is at a distance 14*12 = 168 miles east of the port.
The second boat is at a distance
28*12*cos(30) = 291.0 miles north
and
28*12*sin(30) = 168.0 miles east
of the port.
Since their Eastward displacement is the same, the distance between the two is the Northwards displacement of the second boat = 291.0 miles.
Determine second third and 12TH harmonic of a sine wave?
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
What trigonometric function Is most like an insect that Is ill?
The tangent function, perhaps. Tan is an Ant that is messed up.

Are trigonometric functions used to find the acute angles of a right triangle?
they can be, depending on the information that you are given. If you know lengths of sides, then YES.
How do you find an angle of a triangle?
There are many ways of finding angles in triangles...one of which is to get a protractor, of course...
Also, if you know two angles, you can find the third by just subtracting the sum of the two angles from 180, which is the total number of degrees in any triangle.
The cosine function has an absolute value that cannot exceed 1. Therefore the is no angle x such that cos(x) = 3.
That is, there is no angle x such that x = cos^-1(3).
