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. Note, however, that this does not mean that it's the inverse function to the tangent. 1 + tan2θ = sec2θ. By the choice ( 0, π) we have that cot − 1. x = 1 tany. The arccot is used to obtain an angle from the cotangent trigonometric ratio, which is the ratio between the side adjacent to the angle and the side opposite to it. Thus, we can write cot θ = 1/tan θ and tan θ = 1/cot θ. θ = arccot(1) θ = arccot ( 1) Simplify the right side. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle:. Hence, it is proved that c o t A-1 2-s e c 2 A = c o t A 1 + tan A.

Solve your math problems using our free math solver with step-by-step solutions.3, 4 (iii) - Chapter 8 Class 10 Introduction to Trignometry Last updated at Aug. In a right triangle, the two variable angles are always less than 90° Because the cotangent function is the reciprocal of the tangent function, it goes to infinity whenever the tan function is zero and vice versa. 5. Verified by Toppr. These problems may include trigonometric ratios (sin, cos, tan, sec, cosec and cot), Pythagorean identities, product identities, etc. Since the output of the tangent function is all real numbers, the output of the cotangent function is also all real

Precalculus. What is trigonometry used for? Trigonometry is used in a variety of fields and applications, including geometry, calculus, engineering, and physics, to solve problems involving angles, distances, and ratios. tan (theta) = sin (theta) / cos (theta) = a / b. Cosecant, Secant and Cotangent We can also divide "the other way around" (such as Adjacent/Opposite instead of Opposite/Adjacent ): Example: when Opposite = 2 and Hypotenuse = 4 then sin (θ) = 2/4, and csc (θ) = 4/2 Because of all that we can say: sin (θ) = 1/csc (θ)
