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...
Given an angle measure in degrees that is a multiple of three, we apply trigonometric identities to calculate the exact value of the sine function at that angle. In particular, we use the double angle formula for sine and the tri...

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...
Use the angle in the unit circle to find the exact value of cos(t). Cosine Function in a Unit Circle: For an angle θ in a unit circle, the value of cos(θ) is equal to the x-coordinate of the endpoint of the angle. Similarly, the y-coordinate of the endpoint ...
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...
on a unitcircle we're looking for angles that will have a y coordinate of This means we'll have an angle in thefirst quadrant and an angle in the second quadrant (that we can use the angle in the first quadrant tofind).Here is a unit circle for this situation.Clearly the angle in...
