Final answer:
In the given expression, (vm)(cos)(wt+theta), 'vm' stands for the amplitude of the function.
Step-by-step explanation:
In the given expression, (vm)(cos)(wt+theta), the 'vm' stands for the amplitude of the function. In physics and mathematics, 'amplitude' refers to the maximum distance or quantity a function reaches from its equilibrium position. For example, in the equation of a wave, the amplitude represents the height of the wave from the baseline.
Let's consider an example. If we have the expression (4)(cos)(2x+π/4), the '4' would be the amplitude, which means the function will oscillate between the values -4 and 4.
Therefore, in the given expression, 'vm' represents the amplitude of the function.
