What is the cosine of 3 pi divided by 4?
0.75
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
What angles have the same inverse cosine?
Given an angle A, the angle (2pi - A) has the same cosine. So do the angles that differ from these by 2k*pi radians for all integers k. If you are still working in degrees, you should substitute 180 degrees for pi radians.
When is secant not defined?
The secant of an angle is the reciprocal of the cosine of the angle. So the secant is not defined whenever the cosine is zero That is, whenever the angle is a multiple of 180 degrees (or pi radians).
How do you find the cosine and the sine?
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
What is the arc cosine of pi?
It doesn't exist. The maximum value of the cosine is 1.00, so no angle can have a cosine of (pi), because (pi) is more than 3.
What is the value of cosine at pi?
Looking at a unit circle, cosine is the horizontal coordinate. Pi radians is halfway around the circle (180°), so the coordinate is (-1,0). Cosine(pi) = -1
What is the cosine of 3.14?
3.14 suggest 3.141592.... = pi . Hence Cos (pi radians) = -1
What is cosine inverse of pi?
udefined
What is the sec of pi?
The secant of an angle in trigonometry is defined as the reciprocal of the cosine of that angle. For ( \pi ) radians, the cosine value is -1. Therefore, the secant of ( \pi ) is ( \sec(\pi) = \frac{1}{\cos(\pi)} = \frac{1}{-1} = -1 ).
What is cosine of 2 X 3.1416?
The cosine of 2pi is 1. In fact, for every integer N, the cosine of 2 N pi is 1.
How are sine and cosine curves similar?
The sine curve is exactly the same as the cosine curve shifted pi/2 radians to the left
Is tangent sine divided by cosine?
Yes, except at odd multiples of pi/2 radians, where the cosine is zero so that the division is not defined.
What is the cosine of 3 pi divided by 4?
0.75
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
Is sine and cosine a periodic function?
Yes they are. Both have a a period of 2 pi
What is cos of pi over 2?
The cosine of (\frac{\pi}{2}) (90 degrees) is 0. This is because on the unit circle, the point corresponding to (\frac{\pi}{2}) is located at (0, 1), where the x-coordinate (which represents the cosine value) is 0. Therefore, (\cos\left(\frac{\pi}{2}\right) = 0).
