What is Sin 45 degrees?

The value of Sin 45 degree in decimal form is 0.7071067812.  Sin 45 degree in decimal form is 0.7071067812. Sin is one of the most important functions in trigonometry as it is used to find out the unknown values of the angles and length of the sides of a right-angle triangle.

hope i was clear and that this helps!! ^^

have a great day!!

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

answer: 1+1

step-by-step explanation: 1+1 is at least 2
