The value of integral is known, how to solve out the lower/upper bound of the integral?

As in the picture, all the variables are known except the lower/upper bound, how can I solve out the lower/upper bound? Thank you!

[Steven Lord]

In a case like the one given in the picture, where both the upper and lower bounds are functions of one variable, this is possible. Use fzero to compute a root of this function of x:

f = @(x) (integral(yourIntegrand, -x, x)-knownValue)

where you write your integrand and the known value of the integral in the obvious places.
