2. Trig formula will vary according to the relationship of the slope and dip directions. The best way is to inspect your graphical cross-section and decide whether the dip and slope angles are added or subtracted to form the correct geometry. 3. As an example, given that the dip and slope are inclined in opposite directions: The bearing of A from B is 045º. The bearing of C from A is 135º. If AB= 8km and AC= 6km, what is the bearing of B from C? tanC = 8/6, so C = 53.13º y = 180º - 135º = 45º (interior angles) x = 360º - 53.13º - 45º (angles round a point) = 262º (to the nearest whole number) This video looks at Bearings and shows you how to work them out

The first part of the word is from greek trigon "triangle" and the second part is from greek metron "a measure". These identities are useful whenever expressions involving trigonometric functions need to be simplified. An important application is the integration of non-trigonometric functions: a common technique involves first using the substitution rule with a trigonometric function, and then simplifying the resulting integral with a trigonometric identity.
