Question : If P= and Q = and , determine the value of q
zorro, just go ahead and do the computation.
What is P+ Q? What is (P+Q)^2?
What are P^2 and Q^2? What is P^2+ Q^2?
Set (P+ Q)^2 equal to P^2+ Q^2 and set terms equal component by component. You will have four equations in q. Do they all give the same value for q?
