Question

Find the derivative.

Answer 1

\[y=\frac{ 1+s }{ 1-s }\]\[s=\sqrt{t+1}\]\[t=\frac{ 3x^{2} }{ 4 }\]

Answer 2

' = deri
The first one use quotient rule: (('top *bot)-('bot * top)) / (bot)^2)

Second one I used chain rule: ('out)*('inside) ex: (2x)^2 = 2(2x)(2)

Third is also the quotient rule.
