What is csc sec and cot?
Since there are three sides and two non-right angles in a right triangle, the trigonometric functions will need a way of specifying which sides are related to which angle. Furthermore, the functions are usually abbreviated: sine (sin), cosine (cos), tangent (tan) cosecant (csc), secant (sec), and cotangent (cot).
What is csc cot equal to?
Cosecant, Secant and Cotangent
| Cosecant Function: | csc(θ) = Hypotenuse / Opposite |
|---|---|
| Secant Function: | sec(θ) = Hypotenuse / Adjacent |
| Cotangent Function: | cot(θ) = Adjacent / Opposite |
How do you remember cotangent?
Secant, Cosecant, and Cotangent : Simplifying Trig Functions SOH – CAH – TOA is an extremely useful mnemonic to remember these relationships, and it is likely you have already been introduced to this simple reminder.
How do you memorize secant?
A simple mnemonic is to recall that all 3 definitions involve “reciprocals”, or taking 1 divided by something. Then, look at the first letter of “secant”, it is “s”, and remember that in the reciprocal it is changed to letter “c”. To summarize, sec x=1/cos x. Similarly, for cosec x=1/sin x.
What is sec the opposite of?
The secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.
Is cot tan 1?
Cotangent is not same as tangent inverse. Cotangent function is equal to the reciprocal of tangent function….Thank you.

What is the reciprocal of sin?
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 cot the opposite of?
The cotangent is the reciprocal of the tangent. It is the ratio of the adjacent side to the opposite side in a right triangle.
Which is the opposite side of CSC SEC and cot?
The side which is opposite to ∠B is known as opposite side. The remaining side is known as adjacent side. In the right triangle shown below, find the values of csc A, sec A and cot A. 90° is at ∠B. So the side which is opposite to 90° is known as hypotenuse. The side which is opposite to ∠A is known as opposite side.
How to find the trigonometric ratios CSC, SEC and cot?
The formulas given below can be used to find the trigonometric ratios csc, sec and cot. csc θ = Hypotenuse / Opposite side sec θ = Hypotenuse / Adjacent side cot θ = Adjacent side / Opposite side
Which is the reverse of Sine in CSC?
sin = sine; cos = cosine; tan = tangent; csc = cosecant; sec = secant; cot = cotangent; The abbreviation may also be used with the identity of the angle to which it relates, such as csc α or cot λ. Reciprocal Identities – Defined. Secant is the reverse of cosine. Cosecant is the reverse of sine. Cotangent is the reverse of tangent.
How to memorize sin, cos, tan, and CSC?
An alternate way to remember the letters for Sin, Cos, and Tan is to memorize the nonsense syllables Oh, Ah, Oh-Ah (i.e. / oʊ ə ˈoʊ.ə /) for O/H, A/H, O/A. Or, to remember all six functions, Sin, Cos, Tan, Cot, Sec, and Csc, memorize the syllables O/H, A/H, Oh/Ah, Ah/Oh, H/A, H/O (i.e. / oʊ ə ˈoʊ.ə əˈoʊ hə ˈhoʊ / ).
