Would it be f(x +Δx) = f(x) + Δy? If that's right, how would I get ΔT/2T as Δy?

I have taken the derivative of the 2nd equation above and I got df/dt = (1/(λ*√μ)(1/√T). But I don't know how to get ΔT into the equation

Homework Statement When a guitar string is stretched to have a tension T, it produces a frequency f. You change the tension by a very small amount ∆T . Show that the new frequency of the guitar string is fnew = f ( 1 + (delta T)/2T) For example, a guitar string has tension T = 10N and...
