Find the Tangent Line at the Point y=x^3 , (-1,-1), Find and evaluate at and to find the slope of the tangent line at and . So if the function is f(x) and if the tangent "touches" its curve at x=c, then the tangent will pass through the point (c,f(c)). Start by differentiating y=x 2, which by the power rule gives dy/dx=2x Now you want to plug in x=a to get the slope at the point (a,a 2) dy/dx(a)=2a Now you have the slope of the tangent line, solve for the y-intercept. Find the normal point The normal Solution : y = x 2-2x-3. Next, take the derivative and plug in ???x=4???. tan (471 *+ fill the box and use it to sketch the graph. Find the equation of the tangent line T to the graph of f at the given point. Calculus Derivatives Tangent Line to a Curve 1 Answer at which the tangent is parallel to the x axis. 6.4 Equation of a tangent to a curve (EMCH8) At a given point on a curve, the gradient of the curve is equal to the gradient of the tangent to the curve. Compute the slope of the function Take the derivative of the function 3. As the point q approaches p, which corresponds to making h smaller and smaller, the difference quotient should approach a certain limiting value k, which is the slope of the tangent line at the point p. Find the equation of the line tangent to the graph of {eq}\displaystyle y = f(x) {/eq} at the point {eq}\displaystyle (0, f(0)) {/eq}. The tangent line to a curve at a given point is a straight line that just "touches" the curve at that point. ?, since this is the point at which we’re asked to evaluate.
