(adsbygoogle = window.adsbygoogle || []).push({}); Find the derivative of the following:

y = 1/ COS(t^2)

2. Relevant equations

Here is my attempt

Using (Cos(t^2))^-1

SOlve using the chain rule:

u = t^2

du = 2t

dy/dt = -1.(-sin(u))^(-2) .(2t)

= -2t(-sin(u))^(-2)

= -2t/(Sin(t^2))^2

Is this correct or have I totally used the wrong techiniques?
