What is the opposite side over adjacent side?
The ratio of the adjacent side of a right triangle to the hypotenuse is called the cosine and given the symbol cos. Finally, the ratio of the opposite side to the adjacent side is called the tangent and given the symbol tan.

What is the inverse of csc?
The inverse function of cosecant. Basic idea: In order to find csc-1 2, we ask “what angle has cosecant equal to 2?” The answer is 30°. As a result we say csc-1 2 = 30°. In radians this is csc-1 2 = π/6….
| csc-1 | cosec-1 |

| Arccsc | Arccosec |
How do you find the formula for the adjacent?
To find the formula for the Adjacent, cover up the A with your thumb: This leaves O over T – which means O divide by T, or, Opposite ÷ Tan θ. This tells you that: Adjacent = Opposite / Tan θ
What is opposite over adjacent in trigonometry?
The Tangent Function: Opposite over Adjacent. The third trig function, tangent, is abbreviated tan. This function uses just the measures of the two legs and doesn’t use the hypotenuse at all. The tangent is described with this ratio: opposite/adjacent.
How do you find the opposite of a 45 degree angle?
Substitute the angle θ and the length of the opposite into the formula. In our example, θ = 45° and the opposite is 3 cm. Adjacent = 3 / tan (45°) Adjacent = 3 ÷ tan (45°) Adjacent = 3 ÷ 1 Adjacent = 3
How do you find the opposite and adjacent designations?
Select names for the acute angles in order to determine the opposite and adjacent designations. The easiest way to do this is to draw a picture and label it. The two acute angles are named with the Greek letters theta and lambda.
