trigonometry
SINE
- opposite/hypothenuse
COSINE
- adjacent/hypothenuse
TANGENT
- opposite/adjacent
RIGHT ANGLED TRIANGLES
FINDING THE ANGLE
EG To find COS A it's = adjacent/hypotenuse. Then we have COS-1 by the adj/hyp = A. Solve to find angle A.
NON-RIGHT ANGLED TRIANGLES
- To find the area of a non-right angled triangle the formula is 12bcSINA OR 1/2abSINC or 1/2acSINB
SINE RULE
- a/SINA = b/SINB = c/SINC
COSINE RULE
- a^2 = b^2 + c^2 - 2bcCOSA
