Answer:
⇒ sinA/√(1 – sin2A) = x
? 1 – sin2A = cos2A
⇒ sinA/√cos2A = x
⇒ sinA/cosA = x
⇒ tanA = x

Step-by-step explanation:
Given that:-
√(1+sin2ø)
It can be written as
√(1+2sinøcosø)
we know that sin²A+Cos²A=1
=>√(sin²ø+cos²ø+2sinøcosø)
This is in the form of a²+b²+2ab
here a=sinø and b=cosø
we know that a²+2ab+b²=(a+b)²
=>√(sinø+cosø)²
=>Sinø+Cosø
√(1+sin2ø)=Sinø+Cosø
