Inverse Trig Functions

Inverse Trig Functions. Inverse Trig = Solve for the Angle. INVERSE vs. RECIPROCAL. Its important not to confuse an INVERSE trig function with a RECIPROCAL trig function. The reciprocal of SINE is COSECANT: (sin x ) -1 = csc x The inverse of SINE is ARCSIN : sin -1 x = arcsin x

Angles of Rotation and Radian Measure

Angles of Rotation and Radian Measure. An angle of rotation is formed by two rays with a common endpoint (called the vertex ). In the last section, we looked at angles that were acute. In this section, we will look at angles of rotation whose measure can be any real number. terminal side.
