1. calculator mode
I have the following equation:

y = t2 +tcost

where t = pi/2

however when try to calculate y, I get an answer like ''2.46'', how do I get this in terms of π? (I think I have to change certain settings in my calculator)

oh sorry, here:

Surely the answer is just pi^2/4?

Surely Not

OP you should not need to use a calculator for this question

In such case only use your calculator to calculate the trig values i.e. cos(π/2) = 0 [if you dont remember]

Then treat pi as if it were algebra to leave it in the for of π there is not a calculator mode for this

Oh true, thanks.. if the question was more complicated I would have to change the setting though..?

If it needed a calculator there would be no requirement to give the answer in terms of
