You can put this solution on YOUR website! Approximate, to the nearest 0.01 radian, all angles θ in the interval [0, 2π) that satisfy the equation. (Enter your answers as a comma-separated list.)
(a)sin θ = 0.4798
arcsin(0.4798) = 0.50 and pi-0.5 = 2.64
-----------------------------
(b)cos θ = −0.1201
arccos(-0.1201) = 1.69 or 2pi-1.69 = 4.59
-----------------------------
(c)tan θ = −3.2206
arctan(-3.2206) = 1.88 or 5.01
-----------------------------
(d)cot θ = 2.6318
arccot(2.6318) = 0.36 or pi+0.36 = 3.50
------------------------------------
(e)sec θ = 1.7957
arcsec(1.7957) = 0.98 or 2pi-0.98 = 5.31
-------------------------------------
(f)csc θ = −4.8123
arccsc(-4.8123) = 0.21 or pi-0.21 = 2.93
