Free Trig Measurement Calculator - Given an angle θ, this calculates the following measurements: Sin(θ) = Sine Cos(θ) = Cosine Tan(θ) = Tangent Csc(θ) = Cosecant Sec(θ) = Secant Cot(θ) = Cotangent Arcsin(x) = θ = Arcsine Arccos(x) = θ = Arccosine Arctan(x) =θ = Arctangent Also converts between Degrees and Radians and Gradians
Coterminal Angles as well as determine if it is acute, obtuse, or right angle. For acute angles, a cofunction will be determined. Also shows the trigonometry function unit circle This calculator has 1 input.
What 8 formulas are used for the Trig Measurement Calculator?
sin(θ) = Opposite/Hypotenuse cos(θ) = Adjacent/Hypotenuse tan(θ) = Opposite/Adjacent csc(θ) = 1/sin(θ) sec(θ) = 1/cos(θ) cot(θ) = 1/tan(θ) Coterminal Angles are found by θ ± 360°
What 11 concepts are covered in the Trig Measurement Calculator?
angle
the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
cosecant
the length of the hypotenuse divided by the length of the adjacent side. Also equals 1/sin(θ)
cosine
cos(θ) is the ratio of the opposite side to the hypotenuse.
cotangent
The length of the adjacent side divided by the length of the side opposite the angle. Also equals 1/tan(θ)
coterminal angles
the angles that have the same initial side and share the terminal sides
gradian
defined as one hundredth of the right angle. This is equal to π/200 or 9/10°
radian
a unit of plane angular measurement that is equal to the angle at the center of a circle subtended by an arc whose length equals the radius or approximately 180°/π ~ 57.3 degrees.
secant
the length of the hypotenuse divided by the length of the adjacent side. Also equals 1/cos(θ)
sin
sin(θ) is the ratio of the opposite side of angle θ to the hypotenuse
tangent
the straight line that just touches the curve at that point
