Explain how to find the exact value of sin(570°).
Lena [83]
Quick answer Sin(570) = - 1/2
Comment

570 as an angle contains 1 complete revolution of the terminal arm. The terminal arm begins at the origin and the other (in this case swings around until it records 570° turning around the x axis in an anticlockwise direction.

Anticlockwise means going from 12 o'clock to 9 o'clock to 6 o'clock then 3 o'clock and back to 12 o'clock.

What is 570° (∅) degrees equivalent to?
We keep on subtracting 360 until we get a number between 0 and 360 inclusive.

Written this way 0 ≤∅≤360
570 - 360 = 210°

So we need to find the equivalent of 210° 

Method
210° = 180° + 30°
This means that ∅ is 30° below the x axis in the 3rd quadrant.

Sin(30) = 1/2 
In the third quadrant, the sine is minus. so 
sin(210°) = - 1/2 <<<<<<< Answer

If f ( 4 ) = − 2 , write an ordered pair that must be on the graph of y = f ( x + 4 ) + 1
AlekseyPX

We have been given that

y = f ( x + 4 ) + 1\\&#10;\\&#10;f(4)=-2

Now, we need to find an ordered pair that must be on the graph of

y = f ( x + 4 ) + 1

On substituting x=0 in the above equation, we get

y = f ( 0 + 4 ) + 1\\&#10;\\&#10;y=f(4)+1\\&#10;\\&#10;\text{On substituting the value of f(4)= -2, we get}\\&#10;\\&#10;y=-2+1\\&#10;y=-1

Therefore, the required ordered pair is given by (0,-1)
