## Where is tan equal to 1?

Basic idea: To find tan-1 1, we ask what angle has tangent equal to 1? The answer is 45xb0.

## What is the value of TANX 1?

The first positive value x0 for which tanx1 is, as stated before, u03c04 .

## What does TANX 1 mean?

4. 7. Solving the equation tanx1 means finding every angle x whose tangent is 1. You can start with u03c04, the principal arctangent of 1; the tangent has period u03c0, so (as you said) you need to add integer multiples of u03c0 to that to get the entire set of solutions: {u03c04+nu03c0:nu2208Z}.

## What is tan 1x?

tanu22121x tanu22121(x), sometimes interpreted as (tan(x))u22121 1tan(x) cot(x) or cotangent of x, the multiplicative inverse (or reciprocal) of the trigonometric function tangent (see above for ambiguity)

## What is the angle if tan theta is equal to 1?

The exact value of arctan(1) is u03c04 . The tangent function is positive in the first and third quadrants. To find the second solution, add the reference angle from u03c0 to find the solution in the fourth quadrant.

## What is the value of tan inverse 1?

Answer: The value of tan-1 (1) is u03c0 / 4, and tan-1 (tan 1) is u03c0 / 4.

## How do you get tan theta 1?

The first positive value x0 for which tanx1 is, as stated before, u03c04 .

## What is tan inverse equal to?

The inverse function of tangent. Basic idea: To find tan-1 1, we ask what angle has tangent equal to 1? The answer is 45xb0. As a result we say that tan-1 1 45xb0. In radians this is tan-1 1 u03c0/4

## What is the derivative of tan − 1x?

The derivative of tan inverse x is given by (tan-1x)’ 1/(1 + x2). The differentiation of tan inverse x is the process of finding the derivative of tan inverse x with respect to x.

## Is inverse tan the same as 1 tan?

1/tan(x) is the reciprocal of the tangent function. It is also called the cotangent function. tan^-1x is the arctangent function, defined as the inverse of the tangent function. The -1 is written like an exponent but by convention actually denotes the inverse function.

## Where does tan inverse exist?

The domain of the inverse tangent function is (u2212u221e,u221e) and the range is (u2212u03c02,u03c02) . The inverse of the tangent function will yield values in the 1st and 4th quadrants. The same process is used to find the inverse functions for the remaining trigonometric functions–cotangent, secant and cosecant.
