Okay, so the question, at least the writing, was a bit confusing, but i'm going to take this to mean we want to take the derivative of x, y, cubed.
00:11
Because it doesn't make sense to x, y, to the 34, but i guess to 34, sure, xy to the 34 plus secant of y is equal to 1 plus y to the 4th.
00:33
Okay, so now we want to use implicit differentiation and derive this.
00:37
So the easiest way to do is to just take a derivative of everything.
00:41
So we take d over d x of everything.
00:46
So let's start with the right hand side.
00:48
So derivative of a constant is zero.
00:50
And derivative of y to the fourth, we just use power rule.
00:53
So we get 4 y cubed...
