Question

tan 13pi/3 plz answer​

Answer 1

Answer:

√3

Step-by-step explanation:

we know that tan (a+b)=(tan(a)+tan(b))/(1-tan(a).tan(b))

also tan (13pi/3)=tan(780degrees)=tan(360*2+60degrees)

=(tan(720)+tan(60))/(1-tan(720).tan(60))

now, tan(720)=0      (fact)

so the above equation becomes tan(60)/1=√3
