Which equation is correct

Sergeeva-Olga [200]

1. Two of the main identities used in trigonometry for right triangles (Triangles that have an angle of 90°) are: Sine (Sin) and Cosine (Cos).

Sin x°=Opposite/Hypotenuse

Cos x°=Adjacent/Hypotenuse

2. The inverse of Sinx° is Cosec x°, then:

Cosec x°=1/Sin x°

3. The inverse of Cos x° is Sec x°, then:

Sec x°=1/Cos x°

4. Keeping this on mind, you have:

Cosc x°=Hypotenuse/Opposite

Sec x°=Hypotenuse/Adjacent

5. Therefore, the correct answer is:

The third option: Cosec x°=Hypotenuse/Opposite.

fourth,sixth and thirteenth term in this sequence A(n)= 6+(n+1)(-2) help me to find and describe the explicite formula

OleMash [197]

Hello,

A(n)=6+(n+1)^(-2)=6+1/(n+1)²

$A_{4} =6+ \dfrac{1}{(4+1)^2} =6+ \dfrac{1}{25}= \dfrac{151}{25} \\

 A_{6} =6+ \dfrac{1}{(6+1)^2} =6+ \dfrac{1}{49}= \dfrac{295}{49} \\

 A_{13} =6+ \dfrac{1}{(13+1)^2} =6+ \dfrac{1}{196}= \dfrac{1177}{196} \\
