What does tan 90 a equal?

What does tan 90 a equal?

undefined
The exact value of tan 90 is infinity or undefined.

Which function is equivalent to tan 90 − θ?

tan (90° + θ) = – cot θ.

Why is tan 90 degrees infinity?

In this definition the tan of the angle is the opposite side to the angle divided by the adjacent side to the angle. You can’t have a triangle with a second 90° angle so tan (90°) is undefined. Since any angle having 90° will be on the y-axis, x will be zero. Division by zero is undefined therefore so is tan (90°).

What is value of cos 90 degree?

The value of Cos 90 degree is 0. Cos 90 = 0.

What does tan 90 mean?

tan (90° – x) = cot x. cot (90° – x) = tan x. sec (90° – x) = csc x. csc (90° – x) = sec x.

What is tan equal to?

The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .

What is tan Infinity?

Only Tan 45 is equal to 1. When the value of x goes towards 90, the value goes higher and higher as it goes to an infinity value. tan(infinity) is not =1.

How do you solve tan 90?

tan90∘ is undefined because you can’t divide 1 by nothing. Nothing multiplied by 0 will give an answer of 1 , so the answer is undefined.

Why is tan 30?

Tangent 30 degrees value is one by root 3 (1/√3). Like Sine and Cosine, Tangent is also a basic function of trigonometry.

What is the exact value of tan?

The exact value of tan(0) is 0 .

What is the tangent of tan 90?

Tangent 90 degrees is evaluated as undefined because tan of an angle is equal to the ratio of sin and cos of same angle. Since, sin 90 = 1 and cos 90 = 0, therefore; Tan 90 = sin 90/cos 90. = 1/0. = ∞. As we have got the result as infinity, and we cannot define infinity, therefore tan 90 is undefined.

Why is the tangent of 90 degrees undefined?

Tangent 90 degrees is evaluated as undefined because tan of an angle is equal to the ratio of sin and cos of same angle. Since, sin 90 = 1 and cos 90 = 0, therefore; Tan 90 = sin 90/cos 90

What is the formula for 90 degrees plus Theta?

TRIGONOMETRIC RATIOS OF 90 DEGREE PLUS THETA. Trigonometric ratios of 90 degree plus theta is a part of ASTC formula in trigonometry. Trigonometric ratios of 90 degree plus theta are given below. sin (90° + θ) = cos θ. cos (90° + θ) = – sin θ. tan (90° + θ) = – cot θ. csc (90° + θ) = sec θ. sec (90° + θ) = – csc θ. cot (90° + θ) = – tan θ.

What is the difference between cosine function and tangent function?

Cosine function denotes that for a given right-angled triangle, the cos of angle θ is equal to the ratio of the adjacent side to the angle, and hypotenuse. Tangent function denotes that for a given right-angled triangle, the tan of angle θ is equal to the ratio of the opposite side to the angle, and adjacent side or base.
