B.)

Step-by-step explanation:

Given:

We need to rewrite the given expression as single trigonometric function.

Now According to reciprocal Identities given:

Also Given;

Sow when

and when

Hence the Single trigonometric function is  .

π/36 sec-1

Step-by-step explanation:

From the question we are given the formula below

s = rwt eqn(1)

Where s= π/3m, r=3 m, t= 4 sec

We were not given value of " w" which implies we are required to find out values of" w"

We can make " w " the subject of the formula from eqn(1)

s = rwt

w= s/(rt)eqn(2)

Then substitute for the values in eqn(2)

w= (π/3m ) / ( 3m × 4 sec)

= π/36 sec-1

Hence, the value of the

missing variable is π/36 sec-1
