Differentiating theta with respect to o and h in error analysis

[lovemake1]

Homework Statement

d(theta)=1/sqrt(1-(o/h)^2)

how would you differentaite the function of theta respect to o and h ?
im very new to calculus, i would appretiate if someone giave me a very large step because
im in a hurry to understand this and the sun is soon to rise please..

Homework Equations

The Attempt at a Solution

well the only part i know about error analysis is simple equations like centripetal equations.
but square rooting and this is just too much.

can anyone please guide me through the whole way? and if you don't mind please show me a big step.

division would become multipliation with engative exponent right?

d(theta)=1 * sqrt(1-(o/h)^-2)

This is a poor quality post. How can a differential be equal to a finite function?
