Is the derivative the equation of the tangent line?
The derivative of a function gives us the slope of the line tangent to the function at any point on the graph. This can be used to find the equation of that tangent line.
What is a tangent line to a function?
A tangent line is a straight line that touches a function at only one point. (See above.) The tangent line represents the instantaneous rate of change of the function at that one point. The slope of the tangent line at a point on the function is equal to the derivative of the function at the same point (See below.)
How to find equation of tangent line from derivative graph?
– Substitute the given x-value into the function to find the y-value or point. – Calculate the first derivative of f (x). – Plug the ordered pair into the derivative to find the slope at that point. – Substitute both the point and the slope from steps 1 and 3 into point-slope form to find the equation for the tangent line.
How to solve trigonometric equation with tangent?
Solving Basic Trigonometric Equations Involving Tangent. Step 1: If the tangent can be isolated on one side of the equation with just numbers on the other side, isolate the tangent. Then use the
