Applications of Calculus Ex 5.3 and 5.4

As I promised the complete solutions to Ex 5.4 (on Maximum and Minimum) have now been posted to the Wiki. Also the complete solutions to Ex 5.3 (Tangents and Normals) have been posted. Please note that the last question in 5.3 requires you to find the square root of a negative number ( that is fine if this was Specialist maths but for Methods … doh!).

So are you keeping up? Now is a time of increased effort!
