Explanation Rewriting the given diff eqn (DE) as dy dx − y = 2x, we find that it is a linear DE of the form dy dx yP (x) = q(x) To find its gen soln (GS), we need to multiply it by the integrating factor (IF) e∫P (x)dx Since, P (x) = − 1,∫P (x)dx = ∫ − 1dx = − x ∴ IF is e−x Multiplying the DE by IF, we get, I will just put K equal 1 here and y equals x 3 2x K and put it down here So I am finished This is the answer This is the function y = x 3 2x 1 Its derivative is 3x 2 2 And it passes through the point (1,4) And now for the graph of the function, We can see that it passes through (1,4) We were given the `dy/dx` expression and we have found the "y = " expressionAnswer to Find y if given dy / dx = x^2 3x^{3 / 2} 4 / square root of x and y(1) = 0 By signing up, you'll get thousands of stepbystep
