`% Numerical Integration`

f(x)=int(sym('7+1/sqrt(1-x^2)',1/2,0))

I am stuck on this calculus problem. It is numerical integration, how do i write a code for this problem?It gives me error and i don't know what i am doing incorrectly.

The problem is f(x)= integral sign(7+1/sqrt(1-x^2)). Upper bound of integral sign is 1/2 and lower bound of integral sign is 0.
