Websec(θ) = 1 sec ( θ) = 1 Take the inverse secant of both sides of the equation to extract θ θ from inside the secant. θ = arcsec(1) θ = arcsec ( 1) Simplify the right side. Tap for more steps... θ = 0 θ = 0 The secant function is positive in the first and fourth quadrants. WebIn the third quadrant (III), tan (and cotan) are positive. In the fourth quadrant (IV), cos (and sec) are positive. These just follow from the sign (+ or -) of x or y for each quadrant, as we saw above. These signs are important when …
