Using a calculator, determine the solutions for each equation. The domain is 0≤"theta" (The 0 with the line across it) ≤ 360 degrees
a. tan x=0.75
The two possible solutions i got were 36.9 degrees and 216.9 degrees (i got 216.9 degrees by doing 180+36.9 since it was in quadrant three. BUT in my text book the answer is 323.1degrees.
Is the textbook correct or incorrect? Is my answer correct or incorrect?
If i am incorrect can you please tell me how you get 323.1degrees?
All Chris is saying is that your original calculations were correct if, in fact, the original equation was:
You said your book had the answer as 323.1 degrees.
The only way you're going to get there is by this equation:
This produces a QIV angle of 323.1 degrees.
Sounds like your textbook may have a typo if the above answer is what they expect. They just left out the negative sign.
