Math

• Sine - It is a trigonometric side opposite over to the hypotenuse (SHO)
• Elevation - it is the acute angle formed between the horizontal and the observers line of sight
• Cosecant - It is a trigonometric ratio of the hypotenuse to the opposite (CHO)
• Oblique - triangle with no right angle
• Cotangent - the trigonometric ratio of the adjacent side to the opposite side (CAO)
• Cosine - Trigonometric ratio of all the side adjacent to the hypotenuse (CAH)
• Depression - The acute angle formed between the horizontal and the line of sight to an object located below the horizontal
• Secant - the trigonometric ratio of the hypotenuse to the adjacent side (SHA)
• Tangent - The trigonometric ratio of the opposite side to the adjacent side (TOA)
