Statement 2: UV is unitary.
Select the correct options from the following:
Let *U* and*V* be two unitary matrices. Consider the following statements:\ Statement 1: *U* + *V* is unitary.\ Statement 2: *UV* is unitary.\ Select the correct options from the following: Consider a function *f(x, y)* = *x*² + *y*² − 4*x* − 2*y* + 5. Using gradient descent algorithm, with an initial guess of (3, 2) and learning rate of 0.1, what will be the value of *(x, y)* after one iteration? Figure from the original question paper
