(Click here for an explanation) Category: Calculus: Brief Description: TI-84 Plus and TI-83 Plus graphing calculator program. The slope of the tangent line is the value of the derivative at the point of tangency. Differentiate using the Power Rule which states that is where . To calculate the coordinates of the point where the line is tangent, if you give us the x-coordinate of the point, we only have to replace the x-coordinate with the y-coordinate in the function and we get the y-coordinate, since the y-coordinate coincides with the value of the function for that x-coordinate. If y = f (x) is the equation of the curve, then f' (x) will be its slope. Sketch the tangent line going through the given point. All suggestions and improvements are welcome.

Only one red line intersects the blue curve (locally) at exactly one point, even though every red line has the same slope as the blue line at that point's horizontal component. But the calculator is equipped with a numerical routine that evaluates the derivative at a specified value of x. Calculate the slope of the line tangent to the curve at θ=π/4 and area enclosed byone petalof the curve. How to calculate Slope? It can also be seen that Δx and Δy are line segments that form a right triangle with hypotenuse d, with d being the distance between the points (x1, y1) and (x2, y2). Substitute the $$x$$-coordinate of the given point into the derivative to calculate the gradient of the tangent. Explicit: y=f(x) Now you also know that f'(x) will equal 2 at the point the tangent line passes through. Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line.
