WebWell now let's just take the derivatives. F' (x) is going to be equal to, we're still applying the power rule here, it's going to be three x squared minus 5/6x to the fourth, plus seven over five factorial x to the sixth, I'm just applying the power rule, minus plus, we just keep going on and on and on forever. WebGiven that with the Derivative we are able to get the Slope of tangent lines to our function at any x values, if we set our Derivative expression equal to 0 we are going to find at what x values we have the Slope of our tangent line equaling 0, which would be just a horizontal line. The only time that happens is at min/max values. WebThus, the derivative of a sum is just the sum of the derivatives. Example 1 Find the derivative of 9.8x2 +5x. Solution Since we have already calculated the derivatives of the individuals terms, we can simply apply the sum rule for derivatives. The derivative of the first term is 19.6x and the second is a linear function so its derivative is 5. dash toaster will not stay down
