Answer:
Step-by-step explanation:
cot²(3x)=y
y²-3y+2=0
y²-y-2y+2=0
y(y-1)-2(y-1)=0
(y-1)(y-2)=0
y=1,y=2
cot3x=1
tan 3x=1=tan (π/4)=tan (nπ+π/4)
3x=nπ+π/4=(4nπ+π)/4=(4n+1)π/4
x=(4nπ+1)π/12,n is an integer.
cot 3x=2
tan 3x=1/2
3x=tan^{-1}(1/2)≈26.57°+360n
x≈8.86°+120n
Answer:
1. ratio - 1:4 (side to perimeter)
2. ratio - 4:1 (perimeter to side)
3. ratio - 1: 2 (radius to diameter)
Step-by-step explanation:
for 1. I just put 6/24 which simplies to 1/4. I tried the that with the rest and it equalled to 1/4
for 2. put 24/6 which is 4 (in fraction from 4 is 4/1)
for 3. 4/8 which equals to 1/2
Step-by-step explanation:
The degree of the polynomial is 4.
