Hi;
Using the most famous trig identity known ( already given to you in post #1 ) you can get one answer right away.
round to 4 digits .7259
tan(x) you can do.
The answer was wrong (.7259).
Actually just one question
3. If sin(θ)=−0.6878 and π≤θ≤3π/2, approximate the following to four decimal places.
(a) cos(θ) = (Round to four decimal places.)
(b) tan(θ) = (Round to four decimal places.)
It's looking for an answer to (a) and (b). Im completely confused on this problem , dont know what to do.
