A tangent line of any curve is a line that touches the curve at a point called the point of tangency. For a curve y = f(x), the tangent line at a point x = a on the curve is the line that passes through the point(a, f(a)) on the curve and also has a slope equal to f'(a).
The Tangent Line Formula of the curve at any point 'a' is given as,
f(a) is the value of the curve function at a point 'a'
m is the value of the derivative of the curve function at a point 'a'
