In the equation below, a and c are both vectors of the same size. Given b and d are both scalars, indicated the location of where the dot operator is necessary to perform element-wise operation. Only include dots/periods in the correct locations. A = ((cos (c) + d - a) * (d * a) * tan (b) / (a^2 + c * exp (a) * sin (b)) Note: Write the equation with the correct position of the dot / periods.
