Q. Given the function y=6−5x22x2, find dxdy in simplified form.Answer: dxdy=
Identify Function: Identify the function that needs differentiation.We are given the function y=6−5x22x2. 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 in the form of v(x)u(x), then its derivative is given by (v(x))2v(x)⋅u′(x)−u(x)⋅v′(x). Here, u(x)=2x2 and v(x)=6−5x2.
Differentiate u(x): Differentiate u(x) with respect to x. The derivative of u(x)=2x2 with respect to x is u′(x)=2×2x=4x.
Differentiate v(x): Differentiate v(x) with respect to x. The derivative of v(x)=6−5x2 with respect to x is v′(x)=0−5×2x=−10x.
Apply Quotient Rule: Apply the quotient rule using the derivatives from steps 3 and 4.dxdy=(6−5x2)2(6−5x2)⋅(4x)−(2x2)⋅(−10x).
Simplify Expression: Simplify the expression.(dxdy)=36−60x2+25x424x−20x3+20x3.Notice that −20x3 and +20x3 cancel each other out.(dxdy)=36−60x2+25x424x.
Further Simplify: Further simplify the expression if possible.In this case, the expression cannot be simplified further.
