How are sine and the unit circle related
Web23 de set. de 2010 · Summary. The unit circle is an interesting concept that ties together several important mathematical ideas, such as Euclidean geometry (circles, points, lines, triangles, etc.), coordinate geometry (the x-y plane, coordinates on the plane, etc), and trigonometry (the sine, cosine and tangent ratios). See the 22 Comments below. WebOr it’s a trick question designed to make to say “that’s impossible”. You should ask your teacher for clarification. There's 2 other problems that just defies the sign for each trigonometric functions. a negative tangent on the third quadrant for one problem and a positive cosine on the third quadrant for the other.

WebYou could rearrange the concept a bit to get that the sum of the arguments must be 90 degrees for the sides to be equal, since the sine is the same as the cosine of the complementary angle. We can then set up an equation with just the arguments: 50 - x + 3x + 10 = 90. 2x + 60 = 90. 2x = 30. x = 15. 3 comments.
