Trigonometry test online class 10. . Trigonometry helps us find angles and distances, is used a lot in science, engineering, video games, and more! The triangle of most interest is the right-angled triangle. The right angle is shown by the little box in the corner: Another angle is often labeled θ, and the three sides are then called: Why a Right-Angled Triangle? Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') [1] is a branch of mathematics concerned with relationships between angles and side lengths of triangles. There are six functions commonly used in trigonometry: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). Aug 18, 2025 · Trigonometry, the branch of mathematics concerned with specific functions of angles. Trigonometry is a branch of mathematics that focuses on triangles. Specifically, the relationship between the angles and sides of triangles. The ratios used to study this relationship are called trigonometric ratios, namely, sine, cosine, tangent, cotangent, secant, cosecant. Trigonometry is derived from the Greek word “trigonon” meaning triangle and “metron” meaning to measure. Trigonometry is one of the important branches in the history of mathematics that deals with the study of the relationship between the sides and angles of a right-angled triangle. Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles. Feb 24, 2025 · Trigonometric functions, also known as ‘ circular functions,’ are the ratio between any two sides of a right triangle: the opposite side, the adjacent side, and the hypotenuse with respect to a reference angle θ. Explore the world of trigonometry by mastering right triangles and their applications, understanding and graphing trig functions, solving problems involving non-right triangles, and unlocking the power of trigonometric equations and identities. If you want to find the values of sine, cosine, tangent, and their reciprocal functions, use the first part of the calculator. Trigonometry (named based on a Greek word that loosely translates to "measurement of triangles") is a branch of mathematics that studies the relationships between the sides and angles of triangles. This trigonometry calculator will help you in two popular cases when trigonometry is needed.
