On the formula of alternating current What is the meaning of sin ω t in the formula of alternating current e = e (m) sin ω t? Is it sin ω * t or sin ω t?

On the formula of alternating current What is the meaning of sin ω t in the formula of alternating current e = e (m) sin ω t? Is it sin ω * t or sin ω t?

Is e = e (m) sin (ω T)
Just add a bracket
Where ω is the angular velocity of the generator rotor
