Q. Given the function y=3+2x32x3−3, find dxdy in simplified form.Answer: dxdy=
Identify Function: Identify the function that needs to be differentiated.We are given the function y=3+2x32x3−3. We need to find its derivative with respect to x, which is denoted as dxdy.
Apply Quotient Rule: Apply the quotient rule for differentiation.The quotient rule states that if we have a function y=vu, where both u and v are functions of x, then the derivative of y with respect to x is given by dxdy=v2vdxdu−udxdv. Here, u=2x3−3 and v=3+2x3.
Differentiate u: Differentiate u with respect to x. The derivative of u=2x3−3 with respect to x is dxdu=6x2.
Differentiate v: Differentiate v with respect to x. The derivative of v=3+2x3 with respect to x is dxdv=6x2.
Apply Quotient Rule: Apply the quotient rule using the derivatives from steps 3 and 4.Substitute (du)/(dx) and (dv)/(dx) into the quotient rule formula to get (dy)/(dx)=(3+2x3)2(3+2x3)(6x2)−(2x3−3)(6x2).
Expand Numerator: Expand the numerator of the derivative.Expanding the numerator, we get (dy)/(dx)=(18x2+12x5−12x5+18x2)/((3+2x3)2).
Simplify Numerator: Simplify the numerator.Notice that the terms +12x5 and −12x5 cancel each other out. So, we have (dy)/(dx)=(18x2+18x2)/((3+2x3)2).
Combine Like Terms: Combine like terms in the numerator. Combining like terms, we get dxdy=(3+2x3)236x2.
