Trig Identities Crossword

Across
A solution when solving trigonometric equations where 0˚≤ x < 360˚ or 0 ≤ x < 2pi
sinΘ/cosΘ
Identities based on the inverses of the trigonometric functions
cos(-Θ) = cosΘ and sec(-Θ) = secΘ
Identities based on the inverse of the trigonometric functions
sin(-Θ) = -sin Θ, csc(-Θ) = -csc Θ, tan(-Θ) = -tan Θ, or cot(-Θ) = -cot Θ
1/cosΘ
a² = b² + c² - 2bc*cos(A)
The abbreviation for an ambiguous triangle where the law of cosines can have 0 to 2 solutions
Down
States proportions that hold for the sines of the angles of a triangle and the sides opposite the angles; sinA/a = sinB/b = sinC/c
Identities derived using the Pythagorean theorem; sin² Θ + cos²Θ=1, 1 + tan²Θ=sec²Θ, cot²Θ + 1=csc²Θ
Identities based on the definitions of the trigonometric functions
Identities based on the definitions of the trigonometric functions
1/tanΘ
cosΘ/sinΘ
An equation that has a variable in place of the value of the angle
1/sinΘ
