Lwkylokesh: here they asked tan2A

Lwkylokesh: 2 doesn't have any effect

bhoomiarora2071: Tan 2A = cot (90- 2A)

bhoomiarora2071: As Tan theta = cot 90- theta

Lwkylokesh: so then it ll be cot(90-2A)=cot(A-18) ah?

bhoomiarora2071: Y3ah

bhoomiarora2071: Yeah

bhoomiarora2071: And 90-2A = A -18

Lwkylokesh: thanks bhoomi...

bhoomiarora2071: Wlcm
