| So, what about sine, cosine, and tangent? | |
 | |  |
|
 |
| | |
| These three are the easiest when it comes to Pythagorean identities. | |
| | |
|

|
|
|
| | |
| Okay, explain the fractions or formulas I see them in on my paper. | |
| | |
|
|
| | |
| I'm getting there!! sin(x)=1/csc(x), cos(x)=1/sec(x), tan(x)=1/cot(x). | |
| | |
|
|
|
|
|
|
|
| | |
| So, are the other three just the reciprocal from the ones you just mentioned? | |
| | |
|
|
| | |
| Yes... csc(x)=1/sin(x), sec(x)=1/cos(x), cot(x)=1/tan (x). | |
