3.5: Derivatives of Trigonometric Functions - Mathematics LibreTexts
WebThe Derivative tells us the slope of a function at any point.. There are rules we can follow to find many derivatives.. For example: The slope of a constant value (like 3) is always 0; The slope of a line like 2x is 2, or 3x is 3 etc; and so on. Here are useful rules to help you work out the derivatives of many functions (with examples below).Note: the little mark ’ … WebJan 27, 2016 · Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields.
