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.
Why does cosine x equal cosine negative x?
This is going to require some visualization. Cosine is defined as the x-value on the unit circle. If you picture where a point would be, for example, at the angle of pi/6 (30°) you get a coordinate of (√(3)/2 , 1/2) so cosine is √(3)/2 and sine is 1/2 To find a negative angle you take the reflection across the x-axis. Since this does not chance the x-value, only the y, cosine does not change. The coordinates of -(pi/6) (-30°) are (√(3)/2 , -1/2). cos(-x) = cos(x) sin(-x) = - sin(x)■
What is the cosine of 3 pi divided by 4?

Which case cosine function becomes zero?
For an angle of 90 or 270 degrees. In radians, pi / 2 and 3 x pi / 2.
Where is trigonometric function in negative?
In the domain [0, 2*pi],sin is negative for pi < x < 2*picos is negative pi/2 < x < 3*pi/2 andtan is negative for pi/2 < x < pi and 3*pi/2 < x < pi.Also, the same applies for all intervals obtained by adding any integer multiple of 2*pi to the bounds.
What is the measure of an angle whose cosine 0.5?
The measure of an angle whose cosine is 0.5 is 60 degrees (or (\frac{\pi}{3}) radians) in the first quadrant. Additionally, in the context of the unit circle, the angle can also be 300 degrees (or (\frac{5\pi}{3}) radians) in the fourth quadrant.
Why is cosine negative in the third quadrant?
On a Unit Circle, the cosine is the x coordinate of the point on the circle represented by an angle. Angles greater than 90° (pi/2 radians) and less than 270° (3*pi/2 radians) are to the left of the y-axis, so x is negative. Quadrant I is the upper right quadrant (x positive, y positive) 0° < ɵ < 90° Quadrant II is the upper left quadrant (x negative, y positive) 90° < ɵ < 180° Quadrant III is the lower left quadrant (x negative, y negative) 180° < ɵ < 270° Quadrant IV is the lower right quadrant (x positive, y negative) 270° < ɵ < 360°
What is the rate of change from x and pi to x 2 and pi trig graph with points at 0 negative 4 and pi over 2 0 and pi 4 and 3 pi over 2 0 and 2 pi negative 4 8 over pi pi over 8 negative 8 over pi nega?
To find the rate of change in the given trigonometric graph, we need to analyze the change in the y-values as the x-values transition from one point to another. For the points provided, we can calculate the differences in y-values between consecutive x-values, focusing on the transitions. Without specific pairs of x-values to compare, the overall rate of change can be inferred as varying due to the periodic nature of trigonometric functions, typically oscillating between maximum and minimum values.

How fast would the Earth be actually spinning in Toronto?
Let's use these numbers: (There's some rounding and some assumptions here,but these are plenty close enough.)Earth's diameter: 7,926 milesEarth's period of rotation: 24 hoursToronto's north latitude: 43° 40' = 43-2/3 degreesDiameter of the circle that Toronto rotates on = [ 7,926 cosine(43-2/3) ] milesCircumference = pi x diameter = (pi) (7,926) cosine(43-2/3)Speed in miles per hour = circumference / 24 =(pi/24) (7,926) cosine(43-2/3) =750.5 miles (1,207.8 km) per hour
