Trigonometry Resources
| General Resources | College Algebra | Pre-Calculus | Calculus 1&2 | Linear Algebra |
| The main identity of Trigonometry is: cos(t)2+sin(t)2=1. Remember: cos(t)2=cos(t)·cos(t) and sin(t)2=sin(t)·sin(t). |
| This implies that cos(t)2=1-sin(t)2=[1-sin(t)]·[1+sin(t)] and that sin(t)2=1-cos(t)2=[1-cos(t)]·[1+cos(t)] . |
| To simplify Trigonometric formulae and verify Trigonometric identities try re-writing all the Trigonometric functions in them in terms of cos(t) and sin(t). |
| Thus tan(t)=sin(t)/cos(t); ctn(t)=cotan(t)=cos(t)/sin(t); sec(t)=1/cos(t); csc(t)=cosec(t)=1/sin(t). |
