Step 1: Differentiate both sides of the equation with respect to x.
The given equation is sin(x2y3)+3x3y2=6.
dxd[sin(x2y3)+3x3y2]=dxd[6]
dxd[sin(x2y3)]+dxd[3x3y2]=0
Step 2: Differentiate the first term, sin(x2y3), using the chain rule.
Let u=x2y3. Then dxd[sin(u)]=cos(u)dxdu.
To find dxdu=dxd[x2y3], we use the product rule, where f=x2 and g=y3.
dxd[x2y3]=dxd[x2]⋅y3+x2⋅dxd[y3]
=(2x)y3+x2(3y2dxdy)
=2xy3+3x2y2dxdy
So, the derivative of the first term is:
dxd[sin(x2y3)]=cos(x2y3)(2xy3+3x2y2dxdy)
Step 3: Differentiate the second term, 3x3y2, using the product rule.
Here, f=3x3 and g=y2.
dxd[3x3y2]=dxd[3x3]⋅y2+3x3⋅dxd[y2]
=(9x2)y2+3x3(2ydxdy)
=9x2y2+6x3ydxdy
Step 4: Substitute these derivatives back into the equation from Step 1.
cos(x2y3)(2xy3+3x2y2dxdy)+9x2y2+6x3ydxdy=0
Step 5: Expand the equation and group terms containing dxdy.
2xy3cos(x2y3)+3x2y2cos(x2y3)dxdy+9x2y2+6x3ydxdy=0
Move terms without dxdy to the right side:
3x2y2cos(x2y3)dxdy+6x3ydxdy=−2xy3cos(x2y3)−9x2y2
Factor out dxdy from the left side:
(3x2y2cos(x2y3)+6x3y)dxdy=−2xy3cos(x2y3)−9x2y2
Step 6: Solve for dxdy.
dxdy=3x2y2cos(x2y3)+6x3y−2xy3cos(x2y3)−9x2y2
Step 7: Simplify the expression by factoring common terms from the numerator and denominator.
Factor −xy2 from the numerator:
Numerator =−xy2(2ycos(x2y3)+9x)
Factor 3xy from the denominator:
Denominator =3xy(xycos(x2y3)+2x2)
Now, substitute these factored forms back into the expression for dxdy:
dxdy=3xy(xycos(x2y3)+2x2)−xy2(2ycos(x2y3)+9x)
Cancel xy from the numerator and denominator (assuming $
