Question

find the value of tan(cosec^-1 65/63)​

Answer 1

Step-by-step explanation:

tan (cosec⁻¹ 65/63) = 3.94

Explanation:

Given that

tan (cosec⁻¹ 65/63)

 ∵  cosec⁻¹ 65/63 = sin⁻¹ 63/65

     cosec⁻¹ 65/63 = sin⁻¹ 0.9692

                    ∵ We know that   y = sin x  ⇔ x ∈ [ -π/2 , π/2 ]

     cosec⁻¹ 65/63 = 75.75

So

tan (cosec⁻¹ 65/63) = tan 75.75 = 3.94

The answer is

tan (cosec⁻¹ 65/63) = 3.94
