Across
- 2. the radian, denoted by the symbol rad, is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics
- 6. equation - is one that involves one or more of the six functions sine, cosine, tangent, cotangent, secant, and cosecant.
- 11. theorem It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
- 12. in geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.
- 13. sin 2α - θ = nπ ± α
- 14. The length of the side opposite the angle divided by the length of the hypotenuse
- 15. 1 - θ = (2nπ + π/2) = (4n+1) π/2
- 16. Cos 1-θ =______
- 17. The length of the adjacent side divided by the length of the hypotenuse.
- 18. the secant is the reciprocal of the cosine.
- 19. in trigonometry, a degree is a tiny slice of a circle.
Down
- 1. In mathematics,a unit circle is a circle of unit.
- 3. tan α - θ = nπ + α, where α ∈ (-π/2, π/2]
- 4. θ 1 − cos 2
- 5. secA=hypotenuse/_______=AB/AC=1/cosA
- 7. the tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle.
- 8. tanA= _______ /djacent side=BC/AC=sin A/cos A
- 9. that is, a radius of 1.
- 10. in mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
- 14. is the ratio of the length of the opposite side divided by the length of the hypotenuse.
- 17. cos α - θ = 2nπ ± α, where α ∈ (0, π]
