Find horizontal tangent line using derivative

WebFor finding values of x where the tangent line to the graph is horizontal using the equation 2x^2 + 3x - 1 would you simply find the derivative of the equation and set that answer to 0? And if so, the answer would be -3/4? • ( 2 votes) kubleeka 6 years ago That's correct. The statement "the derivative of 2x^2+3X-1 is 0" implies "x= -3/4".

WebTangent Lines and the Derivative Course: Calculus In calculus, you’ll often hear “The derivative is the slope of the tangent line.” But what is a tangent line? The definition is trickier than you might think. Tangent lines are important because they are the best way to approximate a curve using a line. WebSep 22, 2016 · The other method, without derivative, is to search a line of equation y = x + q that is tangent to the circle. This means that the system { y = x + q x 2 + y 2 − 10 x − 8 y + 18 = 0 has only one solution. madama butterfly libretto opera https://brazipino.com
