    I have my first quantitative exam for A2 OCR physics next week, and the title implies that I'll be recording times for a particular oscillation. I'm really confused as to whether I should go to 1 dp (for example 6.5) or whether I should go to 2dp (6.53) when putting the values for t into a table. Also, if I give my values of 10t and t to 3sf, do I then need to give my value of the gradient of the line to 3sf and also the y-intercept? Thank you!
