Trignometry is all about the trignometric ratios and the table with values of these ratios for different values of angles. If you understand trignometric ratios, then try and break down every problem in terms of these angles itself and you will be able to find answers to each of them. Also, the next part involves some basic trignometric identities, which if you understand the ratios well, shouldn't be a big deal. Try and draw a right angled triangle for every problem and use trignometric ratios to solve all the problems and you will find it very easy.
