 Question 455004: i am new to trigonometry.Could you please explain me every thing about it?Thank you!Answer by Mathematicians(84)   (Show Source): You can put this solution on YOUR website!I guess I can start with the basics. There are 6 basic trigonometric functions. Sine (Sin), Co-sine (Cos), Tangent (Tan), Co-Tangent (Cot), Secant (Sec), Co-Secant (Csc). You only need to remember 3 and remember these simple rules: A way to remember this is that everything corresponds with a "Co". It is suggested you only remember sin, cos, and tan. Consider a right triangle. If you don't remember a right triangle has a 90 degree angle. The three sides of a triangle are usually labeled as opposite, adjacent, and hypotenuse. The hypotenuse is always easy to identify, it's the side directly across from the 90 degree side. Given an angle, the adjacent side will be the side that is right next to the angle while the opposite will be the farthest side from the angle that is not the hypotenuse. I will label O = opposite, A = Adjacent, and H = hypotenuse. X is an angle. Some identities: Hope this helps
