Question

Find the equation of the tangent and normal to y=x^2+x at x=1 , Please show your working out

Answer 1

Tangent line: To write this, you'll need the slope of the tangent line to the curve when x=1. How would y ou find that? Remember that the slope of the tangent line to the curve at x is ALSO the derivative of the function at that x value. Pretty please, find the derivative of y=x^2+x.
