So the equation given to us is 1 plus ln of 2xy equals e raised to 2x minus y and the point given us to 1 by 2 comma 1.
00:16
So this is the point given to us and this is the equation of the function to which we have to find the equation of tangent.
00:22
So we will derivate this.
00:24
So derivation of 1 equals 0 and derivative of ln is equals to 1 by 2xy.
00:32
So we will derivate 2xy.
00:33
So we have to apply chain rule.
00:35
So 2xy dash plus 2y x derivative is 1 and we have to derivate e raised to x derivative is e raised to x and derivative of 2x minus y is equals to 2 minus y dash.
00:55
So this is the derivative and the point given to us is 1 by 2 comma 1.
01:00
So now basically what we will do is we will find the slope.
01:04
So slope is denoted by y dash.
01:06
So what we will do is we will substitute this point here.
01:09
So 2 into 1 by 2 into 1.
01:13
So here 2 will get cancelled out...
