    Post Hi! New user, not very good at differentiation.

    Hello everyone. My name is Brian, I am 58 years old and work as C.N.C machine tool programmer in England. Just started reading book on calculus, I am an absolute beginner having problem differentiating a formula for a maths puzzle. Can anyone provide the solution, from which I will work out where I am going wrong.

    y=SQRT((75-x)^2+625)+SQRT(x^2+4)
