I like the fact derivatives have a shortcut. when i found out how easy it was it blew my mind (sorta). anyway we worked with derivatives again this week, as well as some new problems that involve them. here are some new rules we learned with derivatives
the power rule:
when taking the derivative of something, you take off a power.
formula: X^n = nX^n-1
ex: x^3 + 2x = 3x^2 + 2
the constant rule:
if there is a constant, its derivative is 0
ex: f(x)=3 f`(x)=0
SIN and COS:
basically you switch them up, but the derivative for cos=-sin
ex: -cosx = sinx
