The radian and degrees returns thegreat circle distancebetween two points on a sphere. Notes: on a unit-sphere the angular distance in radians equals the distance between the two points on the sphere (definition of radians) When using "degree", this angle is just converted from radians to de...
A chord is a straight line that connects two points on the circumference of the circle without passing through the center. If the line passes through the center of the circle, it is a diameter. To calculate the chord length, you need to know the radius and either the central angle or th...
The Diameter of a Circle:The diameter of a circle is the longest distance between two points on a circle. It is a line segment that divides the circle into two equal arcs each measuring 180 degrees.Answer and Explanation: The correct answer is: b. 75.79 degrees From the figure above...

Share on Pinterest How to Find the Cosine of an Angle In aright triangle, the cosine of angle α, or cos(α), is the ratio between the adjacent side of an angle and thehypotenuse. Cosine is one of the three primarytrigonometric functionsand is abbreviatedcos. ...
If we can find the radius R of the bolt circle, then this gives us the diameter D. We calculated that: θ = 360 / N Also, A is the spacing between holes. D is the bolt circle diameter. Referencing the diagram above, a triangle can be drawn between the two ends of an arc on th...
Let us supposeθis the angle between the two radii of the arc, andris the radius of the circle then: l=(θ360∘)2πr wherelis the arc length of the circle Answer and Explanation:1 Given that the central angle of the ...
And you cansee it on a map(aren’t those Google guys wonderful!) Distance This uses the ‘haversine’ formula to calculate the great-circle distance between two points – that is, the shortest distance over the earth’s surface – giving an ‘as-the-crow-flies’ distance between the point...
implementation, first consider the symmetry of the four-quadrantatan2(y,x)function. If you always compute the arctangent in the first-octant of the x-y space (i.e., between angles 0 and pi/4 radians), then you can perform octant correction on the resulting angle for any y and x ...
