Question
if secA-tanA=3
then find the value of (5cosA+4cotB)??
jus a hint
Joshi sir comment
First replace cotB by cotA.
because it is wrongly printed by you.
answer by NIKHIL is correct
Read 1 Solution.
(secA-tanA)(secA+tanA)=1
secA +tanA=1/3
from here u can find secA and tanA.
but there is no way to find cotB
