Answer:
sin 45° = [tex]\frac{1}{\sqrt{2} }[/tex]
Step-by-step explanation:
Sin function is a trigonometric function.
Sin value of any angle is defined as a ratio of perpendicular to its hypotenuse.
Now, By definition in a ΔABC, Sin A = [tex]\frac{P}{H}[/tex]
Now, the value of is a constant.
and the value of sin 45° = [tex]\frac{1}{\sqrt{2} }[/tex]
