Document Summary

9. 1 applications involving right triangles notes: sterling. In order to avoid errors when it comes to using a graphing calculator, you must [and can] store unrounded values in memory for the usage in subsequent calculations. What is true and untrue about right triangles: true. You can solve a right triangle if you know what the two sides are: untrue. You can solve a right triangle if you know what the two acute angles are. Whenever you let theta, which is , be an acute angle of any right triangle, which will explain the following functions: Sine sin = opposite hypotenuse y r b c. A + b = 90 x2 + y2 = r2 a2 + b2 = c2 r2 x2 r2 + y2 r2 = r2 r(cid:1)2 r(cid:1)2. = 1 sin2 ( ) + cos2 ( ) = 1 c2 = c2 c2 c2 + b2 a2 c(cid:1)2 (cid:0) a.
