Express as a function :
c.tan (810degrees + theta )
I'm confused between two answers .
1. that it would be tan 90 deg (which is undefined)
2. it would be cot theta
?? can you tell me what i should do to get the right answer.
can you correct the rest for me please?
Express each as a function of theta:
a. sin (270deg + theta)= cos theta
b. cos (pi + theta)= -cos theta
c. tan (810 + theta)= ?????
d. sin (theta - 180)= -sin theta
