# Tan 90-x is equivalent to

The exact value of tan 90 is infinity or undefined.

## What is the formula for tan x sec (90° – x)?

sin (90° – x) = cos x cos (90° – x) = sin x tan (90° – x) = cot x cot (90° – x) = tan x sec (90° – x) = csc x

## How to evaluate tan (90° – Θ)?

Evaluate Tan (90° – θ)? To evaluate tan (90° – θ), we have to consider the following important points. (90° – θ) will fall in the 1st quadrant. When we have 90°, “tan” will become “cot”. In the 1st quadrant, the sign of “tan” is positive.

## What is the formula for degrees sin (90) x?

Cofunction Identities, degrees sin (90° – x) = cos x cos (90° – x) = sin x tan (90° – x) = cot x cot (90° – x) = tan x sec (90° – x) = csc x

## What is the value of tan 90 = 1/0?

We know tan theta=sin theta/cos theta. hence, tan 90 = 1/0. which is undefined!!!! Should I hire remote software developers from Turing.com?

## Is tan 90 theta equal to cot Theta?

tan (90° + θ) = – cot θ.

## What is tan 90 a?

Tan 90 degrees is the value of tangent trigonometric function for an angle equal to 90 degrees. The value of tan 90° is undefined(∞).

## Which function is equivalent to the following tan 90 Theta?

cotθSo cotθ is correct.

## Why is 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 tan 90 is infinity?

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°). Limits have no bearing on whether the function is defined at a given point.

## What is sin 90 as a fraction?

Therefore, sin 90 degree equals to the fractional value of 1/ 1.

## What is cos90 Theta?

cos (90° – θ) = sin θ

## How do you find the trigonometric ratio of 90?

How to Find the Trigonometrical Ratios of 90°? Let a rotating line →OX rotates about O in the anti-clockwise sense and starting from its initial position →OX traces out ∠XOY = θ where θ is very nearly equal to 90°. Take a point P on →OY and draw ¯PQ perpendicular to ¯OX.

## Why is COT 90 defined?

The value of cot 90 is defined since the ratio of cos 90 degrees to sin 90 degrees is defined to a finite value. That means, sin 90° = 1, cos 90° = 0 and cot 90° = cos 90°/sin 90° = 0/1 = 0.

## What is tan30 value?

In trigonometry, the tangent of an angle in a right-angled triangle is equal to the ratio of opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by tan π/6 in terms of radians. The exact value of tan 30° is 0.57735. Tan 30° = 1/√3 = 0.57735.

## What is sin60 value?

Therefore, the exact value of sin 60 degrees is √3/2.

## What does tan 45 mean?

Explanation: For tan 45 degrees, the angle 45° lies between 0° and 90° (First Quadrant). Since tangent function is positive in the first quadrant, thus tan 45° value = 1. Since the tangent function is a periodic function, we can represent tan 45° as, tan 45 degrees = tan(45° + n × 180°), n ∈ Z.

## What is sin60 value?

Therefore, the exact value of sin 60 degrees is √3/2.

## What is tan30 value?

In trigonometry, the tangent of an angle in a right-angled triangle is equal to the ratio of opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by tan π/6 in terms of radians. The exact value of tan 30° is 0.57735. Tan 30° = 1/√3 = 0.57735.

## Why is tan 90 and tan 270 undefined?

At 90 degrees we must say that the tangent is undefined (und), because when you divide the leg opposite by the leg adjacent you cannot divide by zero. In the third quadrant the hypotenuse extended will now meet the tangent line above the x-axis and is now positive again.

## What is sin 180 A?

The exact value of sin 180 is zero. Sine is one of the primary trigonometric functions which helps in determining the angle or sides of a right-angled triangle. It is also called trigonometric ratio.

## What is tan 90?

What is Tan (theta-90)? 3 signs you are losing hair and what to do about it. 38% of women will experience thinning hair, also known as androgenetic alopecia. { tan (90-θ) is equal to cot θ.}.

## What is the sine of theta?

The sine of theta is equal to the cosine of the complement of theta. sin (theta) = cos (90 – theta) cos (theta) = sin (90 – theta) The same thing is true with tangent and complement’s tangent. tan (theta) = cot (90 – theta) and with secant and complement’s secant.
