Prove: cos(3x)=sin(2x)
Vesnalui [34]

Answer:

Step-by-step explanation:

Step-by-step explanation:

By taking ( x = 18°)

<u>L.H.S</u>

cos(3x)=sin(2x)

cos(3x) = cos( 3X18°)= cos (54°)

            = cos[ 90° - (2x18°)]           ∵[  90°- (2x18°) = 54°]

            = ∴ sin ( 2x18°)

      As (x = 18°)

            = sin (2x) = R.H.S

After which value of x does function g exceed function f
nalin [4]
We have that

for x=1
f(x)=1.5  and g(x)=-1
so
g(x) < f(x)

for x=2
f(x)=5  and g(x)=5
so
g(x)= f(x)

for x=3
f(x)=9.5  and g(x)=23
so
g(x) > f(x)

therefore

the answer is
<span>After x=2 function g exceeds function f</span>

HELP ME!,!,,,! I’ve been waiting for 30 minutes
Furkat [3]

Answer:

5/9=1/2

12/13=1

2/13=0

Step-by-step explanation:

These are just based on what I think and also

5/9=0.55... so closer to 0.5 which =1/2

12/13 is just really close to 13/13

2/13 is really close to 0/13 rather than 6.5/13, which is 1/2
