#### Options

• Sides involved in the function
• Sine - sin(x) - opposite/hypotenuse
• Cosecant - csc(x) - 1/sin, hypotenuse/opposite
• Inverse sine - arcsin(x), asin(x) - sin(arcsin(x)) = arcsin(sin(x)) = x
• Inverse cosecant - arccsc(x), acsc(x) - csc(arccsc(x)) = arccsc(csc(x)) = x
• Cosine - cos(x) - adjacent/hypotenuse
• Secant - sec(x) - 1/cos, hypotenuse/adjacent
• Inverse cosine - arccos(x), acos(x) - cos(arccos(x)) = arccos(cos(x)) = x
• Inverse secant - arcsec(x), asec(x) - sec(arcsec(x)) = arcsec(sec(x)) = x
• Tangent - tan(x) - opposite/adjacent
• Cotangent - cot(x) - 1/tan, adjacent/opposite
• Inverse tangent - arctan(x), atan(x) - tan(arctan(x)) = arctan(tan(x)) = x
• Inverse cotangent - arccot(x), acot(x) - cot(arccot(x)) = arccot(cot(x)) = x
