Exercise 11.4 Page No: 11.74

Find dy/dx in each of the following:

1. xy = c2

Solution:

2. y3 – 3xy2 = x3 + 3x2y

Solution:

Given y3 – 3xy2 = x3 + 3x2y,

Now we have to find dy/dx of given equation, so by differentiating the equation on both sides with respect to x, we get,

3. x2/3 + y2/3 = a2/3

Solution:

Given x2/3 + y2/3 = a2/3,

Now we have to find dy/dx of given equation, so by differentiating the equation on both sides with respect to x, we get,

4. 4x + 3y = log (4x – 3y)

Solution:

Given 4x + 3y = log (4x – 3y),

Now we have to find dy/dx of it, so by differentiating the equation on both sides with respect to x, we get,

Solution:

6. x5 + y5 = 5xy

Solution:

Given x5 + y5 = 5xy

Now we have to find dy/dx of given equation, so by differentiating the equation on both sides with respect to x, we get,

7. (x + y)2 = 2axy

Solution:

Given (x + y)2 = 2axy

Now we have to find dy/dx of given equation, so by differentiating the equation on both sides with respect to x, we get,

8. (x2 + y2)2 = xy

Solution:

Given (x + y)2 = 2axy

Now we have to find dy/dx of given equation, so by differentiating the equation on both sides with respect to x, we get,

9. Tan-1 (x2 + y2)

Solution:

Given tan – 1(x2 + y2) = a,

Now we have to find dy/dx of given function, so by differentiating the equation on both sides with respect to x, we get,

Solution:

11. Sin xy + cos (x + y) = 1

Solution:

Given Sin x y + cos (x + y) = 1

Now we have to find dy/dx of given function, so by differentiating the equation on both sides with respect to x, we get,

Solution:
