Simplify tan(0)

Problem

tan(0)

Solution

1. Identify the definition of the tangent function in terms of sine and cosine.

tan(θ)=sin(θ)/cos(θ)

2. Substitute the value 0 for the angle θ

tan(0)=sin(0)/cos(0)

3. Evaluate the trigonometric values for the angle 0 on the unit circle.

sin(0)=0

cos(0)=1

4. Simplify the resulting fraction.

tan(0)=0/1

tan(0)=0

Final Answer

tan(0)=0
