Evaluate each expression if r=-1, n=3, t=12, v=0, w=- 1/2. n^2r-wt

The given expression is

And it is given r=-1, n=3, t=12, v=0, w=- 1/2 .

And we have to find the value of expression using these values .

So we substitute these values for the variables and evaluate the expression. And on doing so,we will get

Therefore the value of the expression with the given values is -3 .
