... 2: Now click the button “Submit” to get the equivalent expression. Step 3 ... (x+3), which is called the equivalent expression. ) Volume = √ √ S (3-3x-241) dy dx. Y=2-2x. = S (3Y-3xY~ ~²) | x - - xxx. O. =S (3x²-6x+3) dx. (x³-3x²+3x) 16 = 1 dx. X. 2. 07. Y=x3 z = 1/2 (6-6x-3×). S = 3-3x- ... (3x + 2y)y' + 2x + 3y = 0 where y(0) = 2 · solve t + arctan(y(t)) + (t + y(t) ... Solve a Riccati equation step by step: x^2 v'(x) + 2 x v(x) = x^4 v(x)^2 + 4. (xA+yB)·C = (x+5y, x+2y,−x−4y)·(2,2,3) = 2x+ 10y +2x+4y −3x−12y = x+2y. Therefore (xA + yB) · C = 0 if and only if x = −2y. This means that the vectors xA + ... Each equation, separately, has an infinite number of ordered pair (x,y) solutions. There is only one point where the two linear functions x + y = 24 and 2x - y ... 3(x − 1)³ (x − 2) (x-3)2. Which of the following statements is correct ... Suppose that 3x²y²+2x-4y = 1. Find the derivative dy at the point (1,1) ... Using the following equation, x 2 + 2x + y 2 + 4y = 20 we get the centre as (-1, -2) and radius r as 5. In this case, we multiply the first equation by 4 to give 12x+4y=28.Then minus the 2nd equation from this to give 10x+0y=20.Now divide by 10 to get x=2. 4 9 XY X 4 Y 9 49315 9 49 2 Z4 2 Z[ \4 4 1 9 ]1 Z19 Z4 5 4 54 9 5 31 4 31 2 Z ^1 5 2219 5 Y 5 31 19 Y Z42 45Y 9 994 1 9 Z45 Z4 Z ^1 [ Z454 4 1^24Y 54 49 2 9919 ...
