Okay, so in this exercise we have our function y equal to secant of e to the 4x multiplied by sine of x squared.
00:13
Okay, let's find the derivative of this function.
00:18
Well, thanks to the product rule we are gonna have the derivative of this one multiplied by this one plus this one multiplied by the derivative of this one.
00:40
Okay, the derivative of this one is easy to compute.
00:44
This is 2x cosine of x squared thanks to the chain rule.
00:52
Okay, now let's compute the derivative of this one.
00:55
Well, thanks to the chain rule, we are going to have the derivative of secant evaluated at e to the 4x, which is secant tangent.
01:05
So secant e to the 4x, tangent e to the 4x.
01:10
Perfect...
