Answer:
secA +tanA=√(b+a) /(b-a)
Step-by-step explanation:
Given, sinA=a/b
we know, sin^2 A + cos^2 A=1
=> cos^2 A =1 - sin^2 A
=> cosA = √(1-sin^2 A)
=> cosA = √(1- a^2/b^2)
=> cosA = √(b^2 - a^2) /b
Now, secA + tanA
= 1/cosA + sinA/cosA
= (1+sinA) /cosA
= (1+ a/b) /√(b^2 - a^2) /b
= b(b+a) /b√(b+a) (b-a)
= √(b+a) /(b-a)
