Test 2

See here for full details.

This Week

In lectures, we covered sections 4.3 to Summary 4.5.5 inclusive.

In the tutorial we answered Q. 9 (ii) from Exercise Sheet 1, Q. 10 (iii), 16 from Exercise Sheet 3 and Q.2 from Exercise Sheet 4.

Problems

You need to do exercises – all of the following you should be able to attempt.

When asked to find the critical points of a function defined on the entire real line (rather than just on a closed interval [a,b]), the ‘endpoints’, \pm\infty are not considered critical points.

Finding the limit as x\rightarrow\pm\infty means find an asymptotic.

‘Horizontal’ asymptotes are asymptotics.

Convex is concave up and concave is concave down.

Do as many as you can/ want in the following order of most beneficial:
