this week in calc i learned how to find a derivative using a shortcut. you can use this shortcut to lessen the length of time it takes to find the derivative of polynomials or if the number is a constant then the derivative is automatically zero.
you do this by taking the exponent of the variable and setting it in front of the variable then subtracting one from the exponent and setting it as the new exponent of the variable.
for example: f'(x)=x^5
f'(x)=nx^n-1
f'(x)=5x^4
