A diﬀerential equation (de) is an equation involving a function and its deriva-tives. Diﬀerential equations are called partial diﬀerential equations (pde) or or-dinary diﬀerential equations (ode) according to whether or not they contain partial derivatives. The order of a diﬀerential equation is the highest order derivative occurring.

This section will deal with solving the types of first and second order differential equations which … Differential equations have a derivative in them. For example, dy/dx = 9x. In elementary algebra, you usually find a single number as a solution to an equation, like x = 12. But with differential equations, the solutions are functions.In other words, you have to find an unknown function (or set of functions), rather than a number or set of numbers as you would normally find with an equation View 55.

Sine and cosine are the unique differentiable functions such that Differentiating these equations, one gets that both sine and cosine are solutions of the differential equation Applying the quotient rule to the definition of the tangent as the quotient of the sine by the cosine, one gets that the tangent function verifies In this section we define the Fourier Cosine Series, i.e. representing a function with a series in the form Sum( A_n cos(n pi x / L) ) from n=0 to n=infinity. We will also define the even extension for a function and work several examples finding the Fourier Cosine Series for a function. cosh(x) = ex + e − x 2 sinh(x) = ex − e − x 2 So, another way to write the solution to a second order differential equation whose characteristic polynomial has two real, distinct roots in the form r1 = α, r2 = − α So, if it was sine two t, we would guess A cosine 2t plus B sine 2t.

f(4)(x)=cos(x). Sådär! Nu har vi de 5 första derivatorna, vilket borde vara tillräckligt för att approximera Taylorpolynomet så
