I donโt really hate them, as my teachers are a lot more forgiving if an assignment is late, although I do have a complaint, but itโs largely unavoidable. That is the fact that you donโt get face-to-face help from a teacher, for me, I can only really ask questions once a week during a streaming session. I donโt think my teacher can use email to assist me with trig identities. Other than that, though, i enjoy sleeping in and the smaller amount of homework. A good formula sheet will take care of those. The one to remember is sin^2 + cos^2 = 1, sin^2(theta) = 1/2 - 1/2* cos(2* theta), cos^2(theta) = 1/2 + 1/2 * cos(2* theta). The first one is where everything is derived from, and the last two will make your live much easier when in calc 1 and beyond. Triangle/angle things, yes thats good. I am really thankful that my teacher gives us formula sheet. |

trigo identities (dont be happy too quickly, you will meet them again later, esp in integration)

trigo identities (dont be happy too quickly, you will meet them again later, esp in integration) I already met the trigonometric identities.. I found it easier than I thought |

I found it easier than I thought its just knowing when to identify (lol) and apply them that turns people off. Memorising them is quite manageable since most can be derived |

I get the basics, but itโs when Iโm confronted with equations like this
โIf sec(theta - pi/2) =-1.04, find csc(-theta)โ that it gets mildly confusing

Good luck in algebra comrade!

sin^2 + cos^2 = 1
The good old phytagoras...
Drawing one time a triangle inside a circle (I did it most times in the beginning of a test - and this is no cheating) makes it easy to remember, write sin and cos instead of a and b. And c is in a circle with r=1 always 1...
Very useful when you don't have a calculator by the hand (you see direct what is sin135 or cos135)

In a few more days the fall of Berlin will be 75 years old, if any of you know a WW2 veteran talk to them and ask them about there story, because they won't live forever and already the great war soldiers are sadly gone.

Sadly, there only a few ww2 veterans, as they are old now, and also there is a threat near them now |
