Q1: Square root computation (7 points) The assignment is to write code for numerically finding a number's square root. The built-in math library function sqrt) can already do this, of course but this is assigned to you as ia problem so you can gain coding experience. Create a function with the following signature, then use it in main() as shown: double mysqrt (double x); // eg. mySqrt(4) will return 2 int main() double s mySqrt(5); cout
