Hi guys
I don't really recall these kinds of limits appearing in 2 unit, could someone please sketch generally how to go about these types of qns ?
Q1 & Q2 are examples

1. remember that l



This can be generalised by letting x = fatima96 (where fatima96 is anything)



2. Convert cosine into sine using complementary angles

1. remember that lim (x-> o) (sinx)/x = 1

2. Convert cosine into sine using complementary angles

Thanks mate, much appreciated

What about cos theta? How would you go about Q2?
