Study Strategy

1. To memorize the Trigonometric identities, I just did lots of Trigonometric identities problems (the exercises sheet). Hoped that I would remember the identities if I used it a lot.

    Advantages:

• Practicing and remembering at the same time.
• Knowing different kinds of problem.

    Disadvantages:

• Taking more times to try to solve the problems while looking back and forth at the identities.
• Head-aching.

--> Not recommended.


2. To memorize the Log and Exponents identities, I wrote down them on a piece of paper over and over again, until i didn't need to look back at the identities to remember.

    Advantages:

• Remember better (at least to me).
• Can ask other people to check for you. 

     Disadvantages:

• Time and paper consuming. 

--> Better than the first strategy.
