# What is sec theta by Tan Theta?

## What is sec theta by Tan Theta?

sec(theta) = 1 / cos(theta) = c / b. tan(theta) = sin(theta) / cos(theta) = a / b. cot(theta) = 1/ tan(theta) = b / a. sin(-x) = -sin(x) csc(-x) = -csc(x)

What is the relation between SEC Theta and tan theta?

Tan (90° – θ ) = Cot θ Sec (90° + θ ) = Cosec θ Sec (90° + θ ) = Cosec θ Sin (270° – θ ) = – Cos θ…Trigonometry – Formulas, Identities, Functions and Problems.

What is the formula of sec theta minus one?

Explanation: Using the Identity : sec2θ=tan2θ+1 , we have, (secθ−1)(secθ+1)=sec2θ−1=sin2θcos2θ .

### What is tan theta equal to?

or, tan theta = sin theta/cos theta (here, theta is an angle) The sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse side, while the cosine of an angle is the ratio of the adjacent side to the hypotenuse side. Hence, sin x = Opposite Side/Hypotenuse Side.

How is sec theta calculated?

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’.

What is tan theta formula?

⇒ tan x = sin x/cos x. or, tan theta = sin theta/cos theta (here, theta is an angle) The sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse side, while the cosine of an angle is the ratio of the adjacent side to the hypotenuse side.

## What is equal to tan theta?

Can you tan theta?

The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side. Like we have for the sine and cosine.

Is sec the inverse of cos?

The secant ( sec ⁡ ) (\sec) (sec) 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.
