MATLAB: I need to make integrat for this equation from 0 to x ,, with respect to x ,,i make several program but i cant reach to the object

Question

y= sqrt(2*m*(E-(a.*x)))

where m,E,A, IS constant

Answer 1

Hi,

syms g(x) a m E 
g(x) = (sqrt(2*m*(E-(a.*x))))
G(x) = int(g(x),x)
pretty(G(x))

gives the indefinite integral, which is:

G(x) =
-(2*2^(1/2)*(m*(E - a*x))^(1/2)*(E - a*x))/(3*a)

or by using pretty:

    2 sqrt(2) sqrt(m (E - a x)) (E - a x)
  - -------------------------------------
                     3 a

Best regards

Stephan
