Integration by substitution: INT[sin(x^2)2x dx] Let u=x^2 du/dx=2 2x dx =du The Cross-Multiplying step I don't understand dx= du/2x INT[sin(x^2)2x dx] INT[sin(u)2x du/2x) INT[sin(u) du] -cos(u) -cos(x^2) Differential Equation: dy/dx = 2x/y y dy = 2x dx The Cross-Multiplying step I don't understand INT[y dy] = INT[2x dx] y^2/2 = x^2 But there are two circumstances under which terms involving dx can yield a finite number. One is when you divide two differentials; for instance, 2dx/dx=2, and dy/dx can be just about anything. Since the top and the bottom are both close to zero, the quotient can be some reasonable number. Differentiating x to the power of something 1) If y = x n, dy/dx = nx n-1 2) If y = kx n, dy/dx = nkx n-1 (where k is a constant- in other words a number) Therefore to differentiate x to the power of something you bring the power down to in front of the x, and then reduce the power by one. A stationary point on a curve occurs when dy/dx = 0.

We recall the standard trig identity for secx. Therefore the integral of secx is the same thing, or identical in other words.

Dy divided by dx

In the former one, y is dependent on x (which is independent) and in the latter, x is dependent on y (which is independent). 6.7K views dydx = 2xy1+x 2 . Step 1 Separate the variables: Multiply both sides by dx, divide both sides by y: 1y dy = 2x1+x 2 dx . Step 2 Integrate both sides of the equation separately: ∫ 1y dy = ∫ 2x1+x 2 dx .

This video explains the difference between dy/dx and d/dxJoin this channel to get access to perks: Isn't "by" also usually used to read a differential-- "dy/dx" > "dy by dx" doesn't strictly mean "dy over/divided by dx". – Neil Coffey Feb 20 '11 at 17:32.

Augustin-Louis Cauchy (1823) defined the differential without appeal to the atomism of Leibniz's infinitesimals. d dx (ey) = d dx (xy) d d x (e y) = d d x (x y) Differentiate the left side of the equation. Tap for more steps ey d dx [y] e y d d x [ y] Begin by setting y=arctan (x) so that tan (y)=x.

dy/dx = ky. dy = ky × dx ( You are simply multiplying both sides by dx) You should then divide both sides of the equation by y. y:dy/y = k dx. Now integrate both sides of the equation. dydx = 2xy1+x 2 .

x/dx=(3-2y)/dy I don't think you'd be confusing anyone at A-level particularly much by giving a brief outline of the problem. Pathological cases aside, the problem is simply that, if you take a function f, integrate it, then differentiate the result, you get f back; however, if you take a function g, differentiate it, then integrate the result, you get g + (some constant) - so, in fact, any function that has 2021-04-12 · dy/dx = 0.
