Quick help with F distribution

We only get the upper % points table for the F distribution.

so to work out F(10,14,0.975) I used the tables and got 3.147, but how do I get F(10,14,0.025)?

Take the reciprocal of the value you get by reversing the degrees of freedom. That is, 1/F(14,10,0.975), using your notation. Or get your values via software! You should get 0.2816576
