Question 1087603
.
Question:
Find the exact value of tan 300 degrees. Use the sum or difference identity.
 
Solution:
300 degrees = 5π/3
=2π-(pi/3)
 
and we know that tan(2π)=tan(0)=0, and tan(π/3)=sqrt(3)
tan(300°)
=tan(2π-(pi/3))
=(tan(2π)-tan(π/3))/(1+tan(&2pi;)*tan(π/3))
=(0-sqrt(3))/(1+0)
=-sqrt(3)



The solution by other tutor is <U>TOTALLY WRONG</U>.
