If √3cosec 2x = 2, then the value of x:
tan 1˚ × tan 2˚× …………………….tan 88˚ × tan 89˚ = ?
Simplify (cos13°+sin 13°) /(cos13°-sin13°)
If tan θ + cot θ = 2 where 0 < θ < 90 ; find the value of tan30 θ + cot 29 θ.
If x tan 60° + cos 45° = sec 45° then the value of x2 + 1 is
The minimum value of 3 sin2 θ + 4 cos2 θ is
