Differentiate with respect to x.
|
|
Step 1: Simplify and look for algebraic rewrites.
Here the equation is a simplified as we need it, and there are no algebra rewrites. You always have to check though. |
|
Step 2: Break the problem down into bitesize chunks based upon the + and – , and identify the derivative rule for each chunk.
Here we have 1 bitesize chunk, .
|
|
Step 3: Apply derivative rules to each of the chunks you identified in Step 2.
– We apply the power rule recipe, Bring the power down — Subtract 1 from the power, to the only chunk, . The power is 3 . So, we bring that 3 down in front and then subtract 1 from that power. |

Final Result: The derivative of is .
Meaning: – The equation for finding the slope of any tangent line at any x-value of is . – The instantaneous rate of change for every x-value of , is found by using the derivative equation, . – The slope of at any single x-value can be found by plugging it into the derivative, .
