Integral Fx Dx

Integral Fx Dx. Integrate x 2 Solution It involves power so applying power rule ∫ fxdx = (x n+1)/n+1 ∫ x 2dx = (x 2+1)/2+1 = (x 3)/3 = x 3 /3 + c Constant Rule When there is a constant value in the function then on integration this constant is taken outside of the integral notation and is multiplied at the end Example 9x 2 Solution ∫kfx.

Time stepping of dx= f (t)*dt constructs the integral or primitive function of the integrand f (t) by summation or quadrature The derivate dx/dt of x (t) is defined as dx/dt = f (t) as another way of writing dx = f (t)*dt that is the derivative of the integral is the integrand.

Integration of f'(x)/f(x)

2 Integral of a function f multiplied by a constant k k f(x) ∫k f(x) dx = k ∫f(x) dx Example Evaluate the integral ∫5 sinx dx Solution According to the above rule ∫ 5 sin (x) dx = 5 ∫ sin(x) dx ∫ sin(x) dx is given by 21 in table of integral formulas hence ∫ 5 sin(x) dx = 5 cos x + C 3 .
