Q. For the following equation, find dxdy.y=−5x5−6x4−3x3+7x2+6Answer: dxdy=
Apply Power Rule: To find the derivative of the function y with respect to x, we will apply the power rule to each term individually. The power rule states that the derivative of xn with respect to x is n⋅x(n−1).
Derivative of −5x5: First, we find the derivative of the term −5x5. Using the power rule, we get:dxdy of −5x5 = −5×5x5−1 = −25x4.
Derivative of −6x4: Next, we find the derivative of the term −6x4. Using the power rule, we get:(dy)/(dx) of −6x4=−6×4x4−1=−24x3.
Derivative of −3x3: Then, we find the derivative of the term −3x3. Using the power rule, we get:dxdy of −3x3 = −3×3x3−1 = −9x2.
Derivative of 7x2: After that, we find the derivative of the term 7x2. Using the power rule, we get:(dxdy) of 7x2=7×2x2−1=14x.
Derivative of constant term: Finally, the derivative of the constant term 6 is 0, since the derivative of any constant is 0.dxdy of 6 = 0.
Combine all derivatives: Now, we combine all the derivatives we found to get the derivative of the entire function y:dxdy=−25x4−24x3−9x2+14x+0.
