Q3
The linear differential equation, dy /dx - 3 / (3x + 2)2y = sin(3x), with y = -2 when x=0, has integrating factor e 1/3x + 2. Write down the modified form of the differential equation. The modified DE is d/ dx() = Find the product AB and use your answer to decide if B is the inverse of A. A= AB= Is B the inverse of A? No Yes If x~ = 5i~- 8j~+ 4k~, y~ = 4i - 5j~ - 3k~ find x~ times y~. The answer is either a vector or a scalar (but not both). Fill in all the boxes, entering NA in any box which is not applicable to the answer. Make sure you enter the minus sign for any negative coefficients and include zero coefficients. The answer is the vector i~+ j~+ k~. The answer is the scalar .Explanation / Answer
