What is Trigonometric functions?
Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.
\(\dfrac{2tan(112.5)}{1-tan^2(112.5)}\)
\(tan2\theta=\dfrac{2tan\theta}{1-tan^2(\theta)}\)
According to double-angle identity θ = 112.5
\(tan2(112.5)\)
\(tan(225)\)
