Half angles trig identities
WebMar 27, 2024 · In addition, half angle identities can be used to simplify problems to solve for certain angles that satisfy an expression. To do this, first remember the half angle identities for sine and cosine: sinα2 = √1 − cosα 2 if α 2 is located in either the first or second quadrant. sinα2 = − √1 − cosα 2 if α 2 is located in the third or fourth quadrant.
