Trigonometric Identities are the identities for trigonometry functions that are true for all the values of variables. A list of trigonometric Identities is used to solve trigonometry-related problems. Find examples at BYJU’S.

cot θ = Adjacent Side/Opposite Side; Reciprocal Identities. The Reciprocal Identities are given as: cosec θ = 1/sin θ; sec θ = 1/cos θ; cot θ = 1/tan θ; sin θ = 1/cosec θ; cos θ = 1/sec θ; tan θ = 1/cot θ; All these are taken from a right-angled triangle. When the height and base side of the right triangle are known, we can find ...

Trigonometric ratios table helps to find the values of trigonometric standard angles such as 0°, 30°, 45°, 60° and 90°. It consists of trigonometric ratios – sine, cosine, tangent, cosecant, secant, cotangent. These ratios can be written in short as sin, cos, tan, cosec, sec and cot.

What is cot i... Question. What is cot in trigonometry? Open in App. Solution. Cotangent. Trigonometric ...

cot a = 1/(tan a) = Adjacent/Opposite = BA/CB Note : Inverse trigonometric functions are used to obtain an angle from any of the angle’s trigonometric ratios . Basically, inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions are represented as arcsine, arccosine, arctangent, arc cotangent, arc secant, and arc cosecant.

The other three functions i.e. cot, sec and cosec depend on tan, cos and sin respectively, such as: Cot θ = 1/tan θ. Sec θ = 1/cos θ. Cosec θ = 1/sin θ. Hence, Cot θ = Base/Perpendicular. Sec θ = Hypotenuse/Base. Cosec θ = Hypotenuse/Perpendicular. Trigonometry Examples. There are many real-life examples where trigonometry is used broadly.

Cotangent Formulas requires the study of a tangent as it's the reciprocal of Tangent. Study more about its definition and solved questions for better understanding at BYJU'S.

Similarly, we can write the trigonometric values for Reciprocal properties, Sec, Cosec and Cot ratios. Sec θ = 1/Cos θ = Hypotenuse / Adjacent side to angle θ = AC / AB; Cosec θ = 1/Sin θ = Hypotenuse / Side opposite to angle θ = AC / BC; Cot θ = 1/tan θ = Adjacent side to angle θ / Side opposite to angle θ = AB / BC; Also, Sec θ ...

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.

If A, B and C are the interior angles of a right-angle triangle, right-angled at B then find the value of A, given that tan 2A = cot(A – 30°) and 2A is an acute angle. Solution: Using the trigonometric ratio of complementary angles, cot (90°- A) = tan A. From this ratio, we can write the above expression as: ⇒ tan 2A = cot (90°- 2A) ….(1)
