In the xy-plane, the unit circle with center at the
origin O contains point A with coordinates (1,0)
and point B with coordinates
(3/4,4/5)
What is the
value of the sine of AOB ?

Answers

Answer 1

We want to find the sine of the angle AOB, we will get that the sine of that angle is equal to 0.73

Remember that the angle, measured counterclockwise from the positive x-axis, defined by a point (x, y) is given by:

θ = Arctan(y/x).

Where arctan(x) is the inverse tangent function.

Now, the angle between point A and point B is just the difference between the angles that define each:

[tex]\theta_A = arctan(0/1) = 0\°\\\theta_B = arctan(\frac{4/5}{3/4} ) = 46.8\°\\[/tex]

Then the angle AOB is just:

AOB = 46.8° - 0° = 46.8°

Then the sine of that angle is:

sin(46.8°) = 0.73

Can someone please tell me whats the Superman tntnnnnn cut called.I've been searching for it for hours but don't know what is called please answer will give brainly.

Answers

Answer:

Well u need to think hard next time

Explanation:

Had Richard Donner completed the Superman sequel back in 1979, it very likely would have been a better film than what Lester ultimately made but 2006's The Donner Cut is simply the best one could do 26 years later. It's also a bit jarring to see test footage in the middle of a movie.

Computer programmer Gus Gorman (Richard Pryor) is hired by financial tycoon Ross Webster (Robert Vaughn) to seize control of a weather satellite and annihilate Colombia's coffee crop. When Superman (Christopher Reeve) manages to thwart the plan, Webster commands Gorman to use the satellite to locate kryptonite, the Man of Steel's mortal weakness. But a missing unknown element in the kryptonite  replaced by Gorman with tar  causes an unintended side effect when presented to Superman.
