Visit the link above for a great review of how to find trig values using the unit circle!

However, in order to do this, you must remember how to find sin, cos, and tan using the sides of a triangle. The values are:sin = opp/hyp cos = adj/hyp tan = opp/adj

Also use the mnemonic SOH CAH TOA to help keep these straight!

Unit 5Applications of Trig

with right and oblique triangles

http://www.youtube.com/watch?v=-6GthfFMMWE - review of angles of depression andelevationUse Heron’s Formula to find the area of a SSS triangle: S=1/2 (a + b + c)A= sqrt[s(s-a)(s-b)(s-c)]

Use the Law of Cosines and the Law of Sines to solve all other oblique triangles.

Finally, be sure to check all answers with your calculator!

THE END!

DO WE LOVE TRIG? OH YES

WE DO!
