How does the unit circle allow the trigonometric functions to be defined for all real numbers instead of just for acute angles?

Every point in the unit circle is identified either by its coordinates (x,y) or by the angle it forms with the x-axis, \alpha.

The trigonometric functions associate with every angle \alpha and the correspondant (x,y) coordinates the two values

\cos(\alpha)=x,\quad\sin(\alpha)=y

This procedure can be done for every angle \alpha, so you don't have to work with acute angles only.

mart [117]

Answer:

7) Decay

8) Growth

9) Growth

10) Growth

Step-by-step explanation:

7) As <em>x </em>increases, <em>y </em>is decreasing because as you add more value to the exponent, 1/3 gets smaller and smaller.

8) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.

9) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.

10) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.

State the largest solution of (x + 3)2 - 4 = 0.
Zinaida [17]
Hello :
(x+3)² -2² = 0
by identite :  a²-b² =(a-b)(a+b)
(x+3-2)(x+3+2)= 0
(x+1)(x+5)=0
x+1=0 or x+5=0
x=-1 or x=-5
<span>the largest solution is : - 1</span>
