Find the equation of the tangent line to the graph of x^2 + y^2 = 1 at the point (1/2, (3^0.5)/2). Find an equation of the tangent line to the graph of y = 6^{-x} at the point (-1, 6). Find an equation of the tangent line to the graph of...
Plug in x=-1 to find f'(-1) = [(-1-1)(2) - (2*-1)(1)] / (-1-1)2 So f'(-1) = [-4-(-2)]/(-2)2 f'(-1) = -2/4= -1/2 We now use the point-slope form equation: y-y1 = m(x-x1) So then we have y-1 = -1/2(x+1) using point slope form and ...
Tangent Line: Using the point-slope form {eq}(y-y_{1})=m(x-x_{1}) {/eq} we can write the equation of the tangent where m is the slope and the point x is already given in the problem and we can find y. Answer and Explanation:1 ...
