The value of sec 90 degrees can be calculated by constructing an angle of 90° with the x-axis, and then finding the coordinates of the corresponding point (0, 1) on the unit circle. The value of sec 90° is equal to the reciprocal of the x-coordinate(0). ∴ sec 90° = undefined(∞).

2024年5月22日 · Sec 90 degrees is equal to the ratio of hypotenuse and adjacent side of 90 degree angle, in a right angle triangle. What is the value of sec 90°? The value of sec 90° is undefined.

Sec 90° – Theta = sec(90° – θ) = sec(1 × 90° – θ) Here, 90° is multiplied by 1, an odd number so sec will change to cosec. Also, 90° – θ comes in the first quadrat. That means, all trigonometry ratios are positive. So, sec(90° – θ) = cosec θ. Therefore, Sec 90 – Theta is equal to Cosec theta.

2024年9月18日 · To evaluate sec (90° – θ), we have to consider the following important points. (90° – θ) will fall in the 1st quadrant. When we have 90°, “sec” will become “cosec”.

In this video, we will learn to find the value secant of (90 degree - x). Following is the URL of video explaining the derivation identity cos(90 – x)https:/...

Find the Exact Value sec(90) Step 1. Rewrite in terms of sines and cosines. Step 2. The exact value of is . Step 3. The expression contains a division by . The expression is undefined. Undefined ...

The expression "sec 90°" is undefined because the secant function, which represents the reciprocal of the cosine function, has a vertical asymptote at 90 degrees, meaning the value approaches infinity as the angle approaches 90 degrees.

Calculate sec(90) sec is found using Hypotenuse/Adjacent. Determine quadrant: Since 0 ≤ 90 ≤ 90 degrees it is in Quadrant I. sin, cos and tan are positive. Determine angle type: 90 = 90°, so it is right. Simplify Formula

Sec 90° – Theta = sec(90° – θ) = sec(1 × 90° – θ) Here, 90° is multiplied by 1, an odd number so sec will change to cosec. Also, 90° – θ comes in the first quadrat. That means, all trigonometry ratios are positive. So, sec(90° – θ) = cosec θ. Therefore, Sec 90 – Theta is equal to Cosec theta.

As a result, you get sec(90°)=1cos(90°)=10, which is impossible to calculate. Using, say, the limit, you can get "near" 90 degrees from the left or right. Near 90°, you'll see that the sec tends to.
