Copy of Discovering Sine, Cosine, and Tangent in Right Triangles
Use the slider and point D to figure out how sin(A), cos(A), and tan(A) are related to a, b, and c and to the size of the triangle. Record your observations in an organized table.
Write out rules that you could use to find the sine, cosine, and tangent of any acute angle in a right triangle. Include a diagram.
- The equations that could use to find the sine could be s=o/n which is A so sin70 degrees is 9.4/10= 0.94 , for cosine you could use c=a/n and in this case is b so cos70 degree is 0.34 and for tangent you could use t=o/d and its the opposite of sin so its c then tan 70 degrees is 2.75.
