The Maths Prof: Turning Points

In this lesson I show you how to find the coordinates of a turning point...

Step 1: Substitute in the coordinates given to find the equation of the curve
Step 2: Differentiate to find an expression for the gradient of the curve
Step 3: Put the gradient equal to zero and solve to find the x coordinate
Step 4: Substitute the x coordinate back into the equation of the curve to find the y coordinate

Easy peasy! 🤗

[pcmjpcmj]

Clear explanation with a good example. Thank You

[DrMilinda]

Thank you so much now I know why we learn differentiation and turning points

[mariadomingues]

anyone else thought her 'a' was a 2 the whole time and was mad confused

[uimagima]

can you make a video on probability as fast as possible, i have an exam in few days
