IN MATLAB, how to solve this question ∫cosh(x) dx in the interval of [1,10]....can anyone give me the script in matlab??please...:|
 

Sry I cannot do it in MATLAB, but you can easily do it by converting into the exponential form...
 

how??...i really need the command in matlab.....annyone who knows it,please give me answer...:cry:
 

Matlab evaluates the indefinite integral

>> syms x
>> int(cosh(x))

ans =

sinh(x)

​
then, the definite integral is: sinh(10)-sinh(1)

And the definite integral

>> syms x
>> int(cosh(x),x,1,10)

ans =

1/(2*exp(1)) - exp(1)/2 - 1/(2*exp(10)) + exp(10)/2

​
Matlab use exponential form sinh(x) = (exp(x)-exp(-x))/2
 

owh...yaa...thnkz u very much...and then,we can't get the real one aswr in matlab?i means the answr like(eg.34.568)<<this...coz using that script,we can get the answr about tht formula only...anyway...thnkx2!:wink:
 

Evaluate the symbolic expression

syms x
eval(int(cosh(x),x,1,10))

​

But for a simple function as cosh (x) does not make sense integrate by symbolic computation or by numeric integration, just use directly the "well known" primitive ∫cosh(x)dx = sinh(x)
