2012-09-06 · By substituting cos `theta` = x and sin `theta` = y into the equation of the unit circle, we can see that (cos `theta` )^2 + (sin `theta` )^2 = 1. Images: This image has been Flagged as sin(A B) = sinAcosB cosAsinB (7) tan(A+ B) = tanA+ tanB 1 tanAtanB (8) tan(A B) = tanA tanB 1 + tanAtanB (9) cos2 = cos2 sin2 = 2cos2 1 = 1 2sin2 (10) sin2 = 2sin cos (11) tan2 = 2tan 1 tan2 (12) Note that you can get (5) from (4) by replacing B with B, and using the fact that cos( B) = cosB(cos is even) and sin( B) = sinB(sin is odd Since -x is the same angle as x reflected across the x-axis, sin(-x) =-sin(x) as sin(-x) reverses it's positive and negative halves sequentially when you think of the coordinates of points on the circumference of the circle in the form p = (cos(x),sin(x)). `sin x = sqrt(1 - cos^2x)` or `sin x = -sqrt(1 - cos^2x)` depending on which quadrant x lies in.
