Ok so this week we finished up with trig and did the test on thursday. Hopefully everyone did well on it and i also found that it was kinda easy. Maybe because i actually studied for this one. Anyway after the test we started Chapter 9 with SOHCAHTOA. This is fairly easy when you learn what the sides of a right triangle is.
The hypotenuse is opposite of the right angle.
The adjacent leg is the side that is opposite of the hypotenuse.
The opposite leg is the side that is opposite the top angle.
What SOHCAHTOA really means is:
SOH: sin(theta)=opposite leg/hypotenuse
CAH: cos(theta)=adjacent leg/hypotenuse
TOA: tan(theta)=opposite leg/adjacent leg
When given a right triangle, all you have to do is plug it in. If it only gives u a hypotenuse and an opposite leg, you would use sin(theta). If it gives u a hypotenuse and adjacent leg, you will use cos(theta) and if it only give you the opp leg and adj leg, you will use tan(theta).
That is basically it for SOHCAHTOA. Theres not much that i dont understand because i find trig pretty easy and this is fairly easy as well.
