Use your understanding of the symmetry of the sine and cosine functions to determine the value of tan(−theta) for all
Dmitriy789 [7]

Answer:

tan(-\theta)=-tan\theta

Odd function

Step-by-step explanation:

We are given that

tan(-\theta)

We have to determine the value of tan(-\theta)and find tangent function is odd,even or neither.

tan(-\theta)=\frac{sin(-\theta)}{cos(-\theta)}

tan\theta=\frac{sin\theta}{cos\theta}

We know that

sin(-\theta)=-sin\theta

cos(-\theta)=cos\theta

By using  identities

Then, we get

tan(-\theta)=\frac{-sin\theta}{cos\theta}=-tan\theta

tan(-\theta)=-tan\theta

Odd function: If f(-x)=-f(x)

Even function:If f(-x)=f(x)

tan(-\theta)=-tan\theta

Therefore, function is an odd function.
