WebHow to find the Equation of a Tangent & a Normal A tangent to a curve as well as a normal to a curve are both lines. They therefore have an equation of the form: \[y = mx+c\] The methods we learn here therefore consist of finding the tangent's (or normal's) gradient and then finding the value of the \(y\)-intercept \(c\) (like for any line). WebIf a tangent line to the curve y = f (x) makes an angle θ with x-axis in the positive direction, then: Slope of the tangent = dy/dx = tan θ. If slope of the tangent line is zero, then tan θ = 0 and thus, θ = 0 which means the tangent line is parallel to the x-axis. In this case, the equation of the tangent at the point (x 1, y 1) is given ...
