How do I simplify tan$\theta$ cos$\theta$ ?
Why is this so hard to do? What pieces of information should I know before doing these?
Can someone just tell me were am I going wrong? I have 5 days to master this before my SAT Practice.
I would brush up on 'basics' but i don't even know how this related to anything ive learnt in trig before...I literally google every identity, am i supposed to remember or somehow derive them??
