I require that a integral be performed in MathCad 14 but can get Mathcad to give me an answer. Below is the code
D:= 4
v:= 20
lamda:=25
E(x):= 6.256*10.x^3.v^2.D
AE:= 4PI(6371000^2)
RD(x):=lamda.(cube root E(x))
AD(x):= PI(RD(x)^2)
FE(x):= 1/(10^(2log(x)-1))
FK(x):= integral (50 to 1500) FE(x).AD(x)/ AE dx
If anyone can explain why mathcad give the answer without doing the integral and showing me how to obtain the correct answer it would be much appreciated. Thank you
