Answer:
1.-
a) θ = 45 ° + 360k
θ = 135° + 360k
b) θ = 45 ° 0 ≤ θ < 360°
θ = 135°
2.-
a) θ = 30° + 360k
θ = 330° + 360k
b) θ = 30° 0 ≤ θ < 360°
θ = 330°
3.-
a) θ = 60° + 360k
θ = 240° + 360k
b) θ = 60° 0 ≤ θ < 360°
θ = 240°
Step-by-step explanation:
1) 2 sin θ = √2
sin θ = √2/2
1.a ) θ = 45 ° + 360k
θ = 135° + 360k
1.b) θ = 45 ° 0 ≤ θ < 360°
θ = 135°
2.
2 cos θ - √3 = 0
2 cos θ = √3
cos θ = √3/2
2.a θ = 30° + 360k
θ = 330° + 360k
2.b θ = 30° 0 ≤ θ < 360°
θ = 330°
3.- √3 cot θ - 1 = 0
√3 cot θ = 1
cot θ = 1 /√3
3.a θ = 60° + 360k
θ = 240° + 360k
3.b θ = 60° 0 ≤ θ < 360°
θ = 240°
Answer:
b possible
Step-by-step explanation:
g(x)=3x^2-2(x+7)/2x+5
g(-1)=3(-1)^2-2(-1)+7/2(-1)+5
Do the numerator first
(3)(-1)(-1)-2(-1)+7
3+2+7
=12
2(-1)+5
-2+5
=3
Numerator= 12 , Denominator=3
Numerator/ Denominator = 12/3=4
Answer: g(-1)=4
