## What is the formula of Sec A?

Secant (sec) – Trigonometry function In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just ‘sec’. … They can be easily replaced with derivations of the more common three: sin, cos and tan.

## What is sec theta?

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). … And the 3 new functions are secant theta, cosecant theta and cotangent theta.

## What is SEC system?

The Sec system utilises two different pathways for secretion: the SecA and signal recognition particle (SRP) pathways. … SRP is a ribonucleoprotein (protein-RNA complex) that recognizes and targets specific proteins to the endoplasmic reticulum in eukaryotes and to the cell membrane in prokaryotes.

## What is trigonometry formula?

Basic Formulas By using a right-angled triangle as a reference, the trigonometric functions or identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side. sec θ = Hypotenuse/Adjacent Side.
