What are cot Cosec and sec?
Secant (sec) is the reciprocal of cosine (cos) Cosecant (cosec) is the reciprocal of sin. Cotangent (cot) is the reciprocal of tan.
What is the function of cosecant?
The cosecant function is the reciprocal of the sine function. The sine function is the opposite side divided by the hypotenuse, so the cosecant function is the hypotenuse divided by the opposite side. The side opposite the right angle is called the hypotenuse, and the other two sides are called legs.
What is the purpose of Secant Cosecant and Cotangent?
Cosecant is the reciprocal of sine. Secant is the reciprocal of cosine. Cotangent is the reciprocal of tangent. When solving right triangles the three main identities are traditionally used.
What is Cosec used for?
The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.
What is cosecant function?
The cosecant function is the relationship between the hypotenuse and the opposite side in a right triangle. We know that cscθ=hypotenuseopposite side θ = hypotenuse opposite side . The numerator always is larger than the denominator as the hypotenuse is the longest side. Thus, the cosecant function is greater than 1.
What are the functions of SEC, cosec and cot?
Sec, Cosec and Cot Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. sec x = 1
What are the names of sin cosec and cot?
Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan.
Which is a function of the formula cosecθ?
cosecθ = 1 sinθ secθ = 1 cosθ cotθ = 1 tanθ These functions are useful in the solution of trigonometrical equations, they can appear in trigono- metric identities, and they can arise in calculus problems, particularly in integration.
How to check the identity of cosecant and cotangent?
Cosecant and cotangent are odd functions, meaning that csc( ) = csc() and cot( ) = cot(). We can check that these identities are true by using that sine is an odd function and that cosine is even: csc( ) = 1 sin( ) = 1 sin() = csc() cot( ) = cos( ) sin( ) = cos() sin() = cot() 275.
