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
How do you find the angle of a cosine?
You mean, you have the cosine, and want the angle? That is called arc-cosine, often written as cos-1x. Your scientific calculator should have a "shift" key or something similar, which you press, followed by the cosine key. That will give you the inverse cosine or arc-cosine.
What is the cosine of 3.14?
3.14 suggest 3.141592.... = pi . Hence Cos (pi radians) = -1
What is cosine inverse of pi?

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.
What is radius of a circle with a central angle of 136 degrees and arc length of 1010cm?
Arc length = 136*2*pi*r/360So r = 360*arc length/(136*2*pi) = 425.5 cmArc length = 136*2*pi*r/360So r = 360*arc length/(136*2*pi) = 425.5 cmArc length = 136*2*pi*r/360So r = 360*arc length/(136*2*pi) = 425.5 cmArc length = 136*2*pi*r/360So r = 360*arc length/(136*2*pi) = 425.5 cm
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
How find radius in a circle given angle and length of arc?
angle of arc/ angle of circle (360°) = length of the arc/ total circumference (2 pi* radius) so you just have to find r then so: angle of arc/ angle of circle (360°) *2pi = length of the arc/ radius radius= ength of the arc/ angle of arc/ angle of circle (360°) *2pi not that hard ;)
How do you find the radius when only the arc length and degree are given?
2*pi*r/Arc length = 360/Degreesince both are a ratio of the whole circle to the arc.Simplifying,r = 360*Arc Length/(2*pi*Degree) = 180*Arc Length/(pi*Degree)
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.
