Question

FILL IN THE BLANKS.

If tan θ = 1 , then find the value of sec θ.
Solution : tan θ = 1 ( given )
Squaring both sides,
tan2 θ = ____ (i)
1 + ____ = sec2 θ . ( complete the trigonometric identity )
∴ sec2 θ = ______.
∴ sec θ = ______.

Answer 1

Answer:

Step-by-step explanation:

Given tan x =1

Find sec x

Tanx=1

x= 45°

secx=sec 45°= √2

Thus sec x=√2
