Question

Find The Value of θ cosθ =4.996

Answer 1

The value of –1 <= cosθ <=1

So, there is no real θ for which the value of cosθ = 4.996.

So, the complex and imaginary solution for the above question is θ = ±2.2916i

where, i = √(–1)

Refer the attachment for the solution

And, the value of θ for cosθ = 0.4996

=> θ = 60° 1' 35''
