(b) Write an equation for the line tangent to the curve at the point (-2, 1) ... 2 G(t, x)=3+² +46 +2 ох. 2. ว. 3+²+4t+2. J. ядай ox (x-1). 2. (x-1)2. Page 2 ... So it becomes μ(3x+2y=2x-y) = μ'(x) (x² + xy). 24. =>. C. = (x+4) if x to & μч0. ... 2: Now click the button “Submit” to get the equivalent expression. Step 3 ... (x+3), which is called the equivalent expression. Jun 2, 2020 ... x^2 + y^2 = 4(x + y).= x^2 -4x + y^2-4y = 0. (x-2)^2 + ( y-2)^2 = 8 this is a circle with center at 2,2 and r = sqrt 8 max will be 2 + sqrt ... (3x - 1)y00 - (3x + 2)y0 - (6x - 8)y = 0. By using the reduction of order formula, a second solution y2(x) is. (a) 3xe−x. (correct). (b) xex. (c) xe2x. (d) x2e− ... May 29, 2012 ... The point (0,0) is on the curve. Since the equation is quadratic, for each slope t, the line y=tx must intersect the curve at a second point. If ... Dec 4, 2014 ... "After we've integrated over y, we're left with a doman in the x-z plane: X=_√4-22. 2 x²+2² = 4. X-2. · x = + √ 4-2² ... (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. Solve for a variable, factor, expand, evaluate fractions, linear equations, quadratic equations, inequalities, systems of equations, matrices. over the compact region. −1 ≤ x ≤ 1, 0 ≤ y ≤ 2. Solution: We look for the critical points in the interior: ∇f = (2x − 2+2y,4y − 2+ ...
