SUMMARY

The integral of the function S (-sin(t)) * exp(cos^3(t)) dt from 0 to 2π evaluates to 0. This conclusion is derived from the properties of the sine function, where the integral of sin(t) over a full period (0 to 2π) is zero. The negative sine function maintains this property, as the exponential factor exp(cos^3(t)) does not affect the overall symmetry of the integral across the specified interval.

Study the SIGNS of the functions very carefully over the full period! :-)
 
I know that
S sin(t) dt
t from 0 to 2pi
is 0
but why also
S (-sin(t))* exp(cos^3(t)) dt
t from 0 to 2pi
?
