Of the flowing four cosine values (radians) which is the greatest A.cos 7.28 B.cos 8.28 C.cos 6.28 D.cos 5.28?
To determine which cosine value is the greatest, we can evaluate each angle. The cosine function decreases in value as the angle increases from 0 to π (approximately 3.14 radians) and then starts increasing again towards 2π (approximately 6.28 radians). Among the options provided, cos 6.28 (which is approximately cos(0) = 1) is the highest, making it the greatest cosine value of the four. Thus, the greatest value is C. cos 6.28.

What are the values of theta of which secant theta is undefined?
Since secant theta is the same as 1 / cosine theta, the answer is any values for which cosine theta is zero, for example, pi/2.
Why can tangent values be greater than 1 but sine and cosine values cannot be greater than 1?
Sine and cosine cannot be greater than 1 because they are the Y and X values of a point on the unit circle. Tangent, on the other hand, is sine over cosine, so its domain is (-infinity,+infinity), with an asymptote occurring every odd pi/2.
What is the Cosine of 62 degrees?
The cosine of 62 degrees is approximately 0.4695. This value can be found using a scientific calculator or trigonometric tables. Cosine values represent the ratio of the adjacent side to the hypotenuse in a right triangle for the given angle.
Why do sine and cosine always have values less than 1?
Sine and cosine functions represent the ratios of the lengths of sides of a right triangle relative to the hypotenuse. Since these ratios involve the lengths of the triangle's legs (which are always shorter than or equal to the hypotenuse), the values of sine and cosine cannot exceed 1. Additionally, on the unit circle, the coordinates of any point (x, y) are constrained within the range of -1 to 1, which further reinforces that the maximum and minimum values of sine and cosine are also limited to this range.
What is the value of the cosine of 55 degrees?
The value of the cosine of 55 degrees is approximately 0.5736. This value can be found using a scientific calculator or trigonometric tables. Cosine values are used in various applications, including physics and engineering, to analyze angles and distances.
How you find cos data?
To find cosine data, you can use a scientific calculator or a trigonometric table that provides cosine values for specific angles. Additionally, programming languages like Python or software tools like Excel can compute cosine values using built-in functions. For angles measured in radians, you can also apply the cosine function directly using the formula cos(θ), where θ is the angle in radians. Online resources and mathematical software can also provide cosine values for various angles quickly.
What are the exact values of the sine and cosine functions of 2pi over 65537 in radians?
The answer will depend on whether the angles are measured in degrees or radians. That information is not provided and so the question cannot be answered.
What is cosine of 3?
Undefined!!!! Can't answer it! All sine and cosine values are between -1 and 1 !!!
What are the values of theta of which secant theta is undefined?
Since secant theta is the same as 1 / cosine theta, the answer is any values for which cosine theta is zero, for example, pi/2.

What are the keypoints for the graph of cosine?
For a general cosine graph, they would be the maximum and minimum values, and the values of the independent variable at which these are attained.Note that the graph of y = cos(x)+2 is never equal to zero, so there may not be any roots.
What does evaluate the expression in both radians and degrees mean?
Radians and degrees are two different systems for measuring the size of an angle. In radians, a full circle is 2pi radians. In degrees, a full circle is 360 degrees. If you want to evaluate an expression in both, then first simplify and evaluate the expression plugging in radian values into your trig functions. The second time, use degree values. On your calculator, you can switch modes between radians and degrees. It should give you the same answer unless you are supposed to leave it written as unevaluated trig functions or something like that. To convert from radians to degrees... radians=degrees * (pi/180)
Sin and cosine values of 0?
sin 0 = 0 cos 0 = 1
What is the Cosine of 62 degrees?
The cosine of 62 degrees is approximately 0.4695. This value can be found using a scientific calculator or trigonometric tables. Cosine values represent the ratio of the adjacent side to the hypotenuse in a right triangle for the given angle.
How do you a graph trig functions?
The basic equation is of general form y = R(x) where (here) R is the Sine, Cosine or Tangent of x, and consequently the Sine and Cosine curves plot oppositely from +1 via 0 to -1 (minus 1) over 180º. The y-values of the Tangent curve goes cyclically from 0 to infinity as x goes from 0º to 90º: it looks odd at first, and you might even think you've gone wrong! Plot in the usual way: left-hand column or top row for suitable increments of x = [angle in degrees], neighbouring columns or rows below for the corresponding ratio values. To get the best out of it, plot 0º to 360º, to give a whole Sine Wave cycle - it and the Circle to which it can be related geometrically, being perhaps the 2 most important curves in Nature!
