Sin 12 in terms of cosine
Webb22 feb. 2024 · \$\begingroup\$ I think they are phase shifting the Euler formula 90 degrees with the J at the front since the real part of Euler is given in terms of cosine but your source function is given in sin. A sin is a 90 degree phase shifted cosine. More obvious if you change Euler to complex cartesian form and multiply by J.

WebbCosine is a cofunction of sine A cofunction is a function in which f (A) = g (B) given that A and B are complementary angles. In the context of cosine and sine, cos (θ) = sin (90° - θ) sin (θ) = cos (90° - θ) Example: cos (30°) = sin (90° - 30°) = sin (60°) http://www.math.com/tables/trig/identities.htm
