Step-by-step explanation:
Tantheta +cottheta=2
Tantheta+1/tantheta=2 (cot=1/tan)
Tan^2theta+1=2tantheta
tan^2theta-2tantheta+1=0
(tantheta-1)^2=0
tantheta-1=0
tantheta=0
tan^12 theta+cot^12 theta
tan^12theta +1/tan^12theta
1+1=2 ☺️
Tantheta +cottheta=2
Tantheta+1/tantheta=2 (cot=1/tan)
Tan^2theta+1=2tantheta
tan^2theta-2tantheta+1=0
(tantheta-1)^2=0
tantheta-1=0
tantheta=0
tan^12 theta+cot^12 theta
tan^12theta +1/tan^12theta
1+1=2 ☺️
