What is the difference between sinus and cosinus?
What is the difference between sinus and cosinus?
Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse .
What is the function of tangent?
What is Tangent Function? The tangent function is one of the main six trigonometric functions and is generally written as tan x. It is the ratio of the opposite side and the adjacent side of the angle in consideration in a right-angled triangle.
What is secant function?
The secant function is a periodic function in trigonometry. The secant function or sec function can be defined as the ratio of the length of the hypotenuse to that of the length of the base in a right-angled triangle. It is the reciprocal of cosine function and hence, is also written as sec x = 1 / cos x.
What is the value cos 60?
1/2
The value of cos 60 is 1/2. Trigonometry is used to study the measurements of right-angled triangles that deals with the parameters such as length, height and angles of the triangle.
What is cos theta cos theta?
The Cos theta or cos θ is the ratio of the adjacent side to the hypotenuse, where θ is one of the acute angles.
What is the cos theta?
The Cos theta or cos θ is the ratio of the adjacent side to the hypotenuse, where θ is one of the acute angles. The cosine formula is as follows: C o s Θ = A d j a c e n t H y p o t e n u s e.
What is cosine used for?
We can use the cosine rule to find the three unknown angles of a triangle if the three side lengths of the given triangle are known. We can also use the cosine rule to find the third side length of a triangle if two side lengths and the angle between them are known.
What is called tangent?
In Geometry, the tangent is defined as a line touching circles or an ellipse at only one point. Suppose a line touches the curve at P, then the point “P” is called the point of tangency. In other words, it is defined as the line which represents the slope of a curve at that point.
What is sec and Cosec?
Secant (sec) is the reciprocal of cosine (cos) Cosecant (cosec) is the reciprocal of sin. Cotangent (cot) is the reciprocal of tan.
