Explanation
Part 1: tan 226
Angle 226 lies in the third quadrant. This can be seen below.
In the above, the principal angle is 226, therefore, the acute angle becomes,
[tex]226-180=46[/tex]Since tan is positive in the third quadrant, therefore
Answer: tan 46
Part B: Sin-46.6
In trigonomtery,
[tex]sin(-a)=-sina[/tex]Therefore;
[tex]sin(-46.6)=-sin46.6[/tex]Answer: -sin 46.6
