Unit Circle Theunit circleis a circle with a radius equal to 1, centered on the origin (0, 0). It is used to calculate the cosine, sine, and tangent of any angle within the circle, although it is most commonly used for easy memorization of thesineandcosineof angles that are multiples...
θ = angle in degrees How to Find Area of a Segment The segment of a circle is the region between the chord and arc connecting the endpoints of the chord. A chord is a line segment that connects any two points on a circle. The segment would be the portion cut off of a sector if ...
Finding the missing side or angle couldn't be easier than with our great tool – right triangle side and angle calculator. Choose two given values, type them into the calculator, and the calculator will determine the remaining unknowns in a blink of an eye! If you are wondering how to f...
Consider a unit circle marked in radians (one radian is a little over 57°).We can use the circle to estimate the values af trigonometric functions.The definition of the sine of angle t issin t=((opposite side))((hypotenuse))But the opposite side of the right triangle formed by the un...
Arc of a Circle Calculator Examples on Arc length Example 1:Find the length of an arc of a circle cut off by a central angle of 4 radians in a circle with a radius of 6 inches. Solution: Center angle, θ = 4 radians, radius, r = 6 inches. Use the arc length formula, L = θ...
The value of arctan 0 in degrees is 0 and the value of arctan 0 in radians is 0. This is because tan 0 = 0 when the angle is in radians or degrees. Learn more about finding the value of arctan 0 along with examples.
