1. Identities of the trigonometric functions of the same argument: 2. Values of the trigonometric functions at specific points: 3. Evenness or oddness: 4. The signs at quarters: 5. Reduction formulas: 6. Solution of the simplest trigonometric equations: sin (x) = a ⇔ x = (-1) n arcsin (a) + n π, n = 0, 1. ∈ Z 🔎 Trigonometric functions (sin, cos, tan) are all ratios. Therefore, you can find the missing terms using nothing else but our ratio calculator! Trigonometry has plenty of applications: from everyday life problems such as calculating the height or distance between objects to the satellite navigation system, astronomy, and geography. Trigonometric Values of Special Angles. s i n α = a c, c o s α = b c, t g α = a b, c t g α = b a. π α = 0 ° = 2 π. sin 0 °. cos 0 °. A scientific calculator supports calculations of trigonometric functions, such as sine, cosine, tangent, cotangent, etc. Using this calculator, you can find the logarithm of a number, raise to a power, find a root square and, moreover, a nth root.. [ tg ] - means tangent of an angle; [ ctg ] - means cotangent of an angle; [ π ] - is a.

Trigonometrie; sin, cos, tg, ctg YouTube

In mathematics, the trigonometric functions are a set of functions which relate angles to the sides of a right triangle. There are many trigonometric functions, the 3 most common being sine, cosine, tangent, followed by cotangent, secant and cosecant. [1] [2] The last three are called reciprocal trigonometric functions, because they act as the. This online calculator computes elementary trigonometric functions such as sine, cosine, tangent, cotangent, secant, cosecant for angle, which can be entered in degrees, radians, or grads A: The basic trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These functions relate the ratios of the sides of a right-angled triangle to the angles in the triangle. $\begingroup$ @J.M.ain'tamathematician: I bet in China they use tg (and I am sure about x-USSR countries). I do not know about India and Pakistan. Perhaps they use tan which they used when they were parts of British empire (just as the cricket). So a lot of people use tg. $\endgroup$ -

In this video I explain what is the sin, cos, tg and ctg of angle. Also I demonstrate how to obtain the main trigonometric equality. Trigonometry - Sin, Cos, Tan, Cot. A circle centered at the origin of the coordinate system and with a radius of 1 is known as a unit circle . If P is a point from the circle and A is the angle between PO and x axis then: The x -coordinate of P is called the cosine of A and is denoted by cos A ; The y -coordinate of P is called the sine of A. Connection of sine and cosine: sin 2 α+cos 2 α=1; Sine and tan connection: sin 2 α=tg 2 α / 1+tg 2 α; Cosine and tan connection: cos 2 α=1 / 1+tg 2 α; To learn more about trigonometric identities, see this related Sum and Difference Identities Calculator. Trigonometry Table In higher mathematics, sin and cos can also be applied to complex and real numbers. All other trigonometric functions are derivatives of sine and cosine. There are only four of them: Tangent (tg) - the ratio of the opposite leg to the adjacent one - tgx = sinx / cosx.

Formule trigonometrice sinus cosinus tangenta cotangenta formula fundamentala triunghi dreptunghic cateta ipotenuza Tabel trigonometric, sin(a+b), sin(a-b), cos2x, sin2x, cos(a+b), cos(a-b), sina cosb The cosine of pi. cos π = cos 180 = -1. Thus, the cosine of pi is the same as the cosine of 180 degrees and it is equal to minus one. 3. The tangent of pi. tg π = tg 180 = 0. Thus, the tangent pi is the same as the tangent of 180 degrees and it is zero.
