the question is this:

FIND, GIVING YOUR ANSWER IN TERMS OF PIE, ALL VALUES OF THETA IN THE INTERVAL " THETA IS GREATER THAN 0 AND LESS THAN 2*PIE FOR WHICH.

a. tan (theta+pie/3) =1

How would you solve

tanA=1?

(Btw it's pi not pie)

Arctan (1) = pi/4

therefore, theta + pi/3 = pi/4

You can do the rest. Remember multiple solutions/ period of tanx is pi

A= tan inverse of 1

Let A = Theta + pi/3
Therefore Tan(A) = 1
Solve for A within your range
substitue all values into A = Theta + pi/3 and solve for theta, check what values of theta are within your range.
