The complex conjugate of x i y is x − i y, so we would conventionally say the complex conjugate of − 3 2 i is − 3 − 2 i Note that the convention is for the i to come after a numeric constant but before a variable #y = 1/3 x 1# So naturally if we consider that a solution to this system will be a point where the line and the circle intersect, we should not be surprised to learn that there will be two solutions One when the line enters the circle, and another when it leaves See this graph graph{(x^2 y^2 9)((1/3)x 1y)=0 10, 10, 5, 5}Weekly Subscription $249 USD por semana hasta cancelar Suscripción mensual $799 USD por cada mes hasta cancelar Suscripción anual $3499 USD por cada año hasta cancelar

Y^2 = x^32x^2 Natural Language;Now, y = x± q x2 −4(x2 −7) 2 = x± √ 28−3x2 2 Take the positive root since y(1) = 3 The restriction on x would be that 28−3x2 ≥ 0 Therefore, − s 28 3 < x < s 28 3 5 Problem 15 (xy2 bx2y)dx(xy)x2 dy = 0 First, for this to be exactQuestion Solve the given differential equation Y' x^1 y = 4x^2y^1 cos x, x > 0 Dy/dx 1/2(tan x)y = 2y^3 sin x dy/dx 3/2x y = 6y^1/3 x^2 ln x y' 2x^1y = 6 squareroot 1 x^2
Y' 2x^1y = 6y^2x^4 2x(y' y^3x^2) y = 0 (x a)(x b)(y' squareroot y) = 2(b a)y, where a, b are constants Y' 6x^1y = 3x^1y^2/3 cos x, x; Example 17 Solve the pair of equations 2/𝑥 3/𝑦=13 5/𝑥−4/𝑦=−2 2/𝑥 3/𝑦=13 5/𝑥−4/𝑦=−2 So, our equations become 2u 3v = 13 5u – 4v = –2 Hence, our equations are 2u 3v = 13 (3) 5u – 4v = – 2 (4) From (3) 2u 3v = 13 2u = 13(2 x) dy dx = 3y This is a First Order separable Differential equation, and we can rearrange as follows 1 y dy dx = 3 x 2 And we can "separate the variables" to get ∫ 1 y dy = ∫ 3 x 2 dx
SOLUTION 15 Since the equation x 2 xy y 2 = 3 represents an ellipse, the largest and smallest values of y will occur at the highest and lowest points of the ellipse This is where tangent lines to the graph are horizontal, ie, where the first derivative y'=0Let the transformation be f(x,y) = (f_1(x,y), f_2(x,y)) The line y = 3 is mapped to x = 0 so f_1(x,3) = 0 for all x This means that we can set f_1(x,y) = M_1(y3) y = 1 Now we know the value of y Let's put this in the first equation and solve for x 2x 3y = 7 2x 3 (1) = 7 2x 3 = 7 Subtract from both sides 2x = 4 Divide both sides by 2 x = 2 The solution to this system of equations is, *drumroll please*, x = 2 and y = 1!
