## What is the value of tan inverse PI by 4?

Trigonometry Examples The exact value of tan(π4) tan ( π 4 ) is 1 .

2tan2theta

## Is Tan Pi undefined?

Because tan(x) is defined as being equal to sin(x)/cos(x), and cos(π/2)=0. So tan(π/2)=1/0, which is undefined because of the division by zero.

## Why is tan PI 2 Infinity?

pi/2 is a right angle. The side opposite the angle tends to 1. The side near the angle tends to 0. The tangent therefore tends to infinity.

## Why is Pi 2 Infinity?

By definition tan is sin/cos and since the sin of pi/2 is 1 and the cos of pi/2 is 0 the tan of pi/2 is an undefined value, because you cannot divide anything by zero. On the other hand, the limit of x as it approaches tan(pi/2) from the left is infinity.
