WebVerifying a Trigonometric Identity Involving sec2θ Verify the identity sec2θ − 1 sec2θ = sin2θ Analysis In the first method, we used the identity sec2θ = tan2θ + 1 and continued to simplify. In the second method, we split the fraction, putting both terms in the numerator over the common denominator. WebDec 20, 2024 · To define the trigonometric functions, first consider the unit circle centered at the origin and a point P = (x, y) on the unit circle. Let θ be an angle with an initial side that lies along the positive x -axis and with a terminal side that is the line segment OP. An angle in this position is said to be in standard position (Figure 1.7.2 ).
